How Junk Yard Wars have inspired us : LUSENET : Junkyard Wars : One Thread

I'm sure many of us can post on this one. How has Junk Yard Wars Inspired us. Have we had any projects we've started after watching the show? Here's My Experiance. After watching the Show I was inspired to Build a Sprint Car/Go Kart. I love The Way A winged Sprint Car looks, and Thought it would be fun to build a mini version. I've Already started Hitting Junk Yards to see what I can get from them to build My Car. I've only got one problem and maybe someone out here can offer a suggestion. I'm not a Mechanic by any means so I'm kinda Stuck on the Motor. I've decided to Get one BRand New rather then a used one from a YArd. I'm looking at a Engine ranging from 10hp-20hp with a horizontal Shaft. I'm not wanting a car that goes super fast or I'd obviously set my sites Higher. So my Question is any suggestions on an Engine that I can get at least 35-40 mph? I was thinking of scrapping a Riding LAwn Mower as I can get several Parts of it that I can use. ANy thoughts? Plus I look Forward to hearing Everyone elses JYW inspired Projects

>>>So my Question is any suggestions on an Engine that I can get at least 35-40 mph?<<<

Try a chainsaw engine. I built many steel-framed go-carts from scratch over the years (without welding), and I ultimately found the chainsaw engine MORE than powerful enough, and much LESS bulky than a small motorcycle engine. This is just raw power with a throttle (though I imagine you could devise a gear box of some sort). NOTE: Make sure you focus great care on your braking system... You'll NEED it. }=]

im considering building a go cart for my kids..and im going to use a smaller displacement motorcycle its pretty much self contained. i.e. clutch,gears sprocket,etc...amen on the suggestion about the brakes!

-- tim (, January 19, 2001.

Don't be too quick to pass up the salvage yard for an engine, JunkMan. You'd be surprised just what you can find available.

You have to remember that most vehicles which end up on the scrapheap after being totalled in an accident are the victims of frame-damage more than anything else. It's impossible to ever repair a warped frame, of course, which is why most cars involved in a serious accident are simply written off. But a good many of the parts used for repairs and even whole rebuilds are scavenged from the scrapheaps. Scrapyards are among the single biggest sources of parts for dealer service departments and repair shops.

Twenty years ago, my best friend and I (then nextdoor neighbours to boot), having just graduated from our respective schools and facing an empty summer ahead, spent two and a half glorious months rebuilding a 1970 Ford LTD (his). The source-engine for the project, a big-block 462 Lincoln motor, came right from the salvage yard. We just went down there one afternoon, told the guy what we wanted, and hopped on his scrap wagon until we got to the pile of engines pulled from wrecked Fords. All of them were in good shape --all their parts intact and not a cracked block among them. A little petrol and a battery hookup and the motor fired up right on the spot. We tore it down anyway to clean the valves and pistons, replace what needed to be replaced in the power-train, and dropped the reassembled motor into the frame two weeks later. Worked like a dream, and you should have heard that motor sing.

Take my word for it --scrapyards are treasure troves. Something I learned years before Junkyard Wars was even thought of.

-- Patrick Degan (, January 19, 2001.

Hey JunkMan , If I was doing it I would use a small(250cc or so)snowmobile engine. They have a centrifugal clutch & the belt drive acts like a transmission. This would be easy to Bodge together & have lots of horse power for your cart, no clutch either. It would easily do 40mph so be safe then sorry, put a roll over bar (roll cage) & seatbeat on it. I was inpired but lastnites show, I wanna build a hovercraft. I got a great plan allready . All I need is the motor & prop. Happy bodging. :)

-- Rick Lawrence (, January 19, 2001.

I've received a few emails already, asking me HOW I built steel-frame go-carts WITHOUT welding. You may be embarrassed to hear the answer. I used threaded 1" plumbing pipe, with all of the angled and threaded joints afforded. You could build a flipping MONUMENT using threaded iron plumbing pipe. Iron plumbing pipe is no longer a building standard (something about steam passing over iron that produced combustible hydrogen gas pockets). On the other hand, the 1" pipe was relatively light-weight in building go-cart frames---Coupled with a light-weight chainsaw engine and two cups of gas-and-oil, the machine could, verily, pull HELL off the cross.

C. Austin


-- Charles Austin (, January 19, 2001.

And one more thing. The chainsaw engine was configured for a different type of load than lawnmower engines. Briggs & Stratton lawnmower engines, for instance, are high-compression, like airplane engines, designed with a low-load shear-pin, which breaks off under rather wimpy loads, leaving the cam to freewheel when you hit dense weeds. Chainsaw engines, on the other hand, are designed for much HIGHER loads, sufficient to cut through an oak stump or launch a go-cart to a velocity MUCH FASTER than many of you will find comfortable. }=]

C. Austin


-- Charles Austin (, January 19, 2001.

And, yes, I understand the difference between iron and steel. My dad was a supervisor with Sheffeild Steel, and I received weekly discourses on the conversion of iron to steel throughout my childhood. Geez, you people are SO picky. }=]

Junkyard Wars inspired me to build a robot. I checked out web sites to see what could be made by a home robot builder and found out that it's kind of expensive and you have to learn a lot of electronics and when you're all done, you just have an ugly pile of electronic parts with minimal functionality that is farther from the robots of science fiction than an amoeba from a human being. But neverfear, I'm still inspired to bodge something else. Maybe I'll go back to work on my unfinished balsa airplane model kits.

-- Richard Manahan (, January 19, 2001.

a Chainsaw engine? Thats interesting as I never consider it since it's so small. No would it matter if my sprint car/go kart will be used off road? THanks for all the suggestions, I'm defenitly taking notes

-- JunkMan (, January 19, 2001.

I live in utah where people throw away old snowmobiles and atvs, Honda three wheelers, tote gotes, all the time in the local scrap yard. Sometimes I luck out and find big atv wheels. My go kart has a briggs and straton 5 hp motor and I enclosed it by putting a snowmobile front end or hood over the engine that is the front end was put in facing backwards {motor is in back). It looks great. You will have to do some cutting and when you do cut; cut a little at a time. Careful once you cut out too much you cannot get it back. Take your time. Caution fiberglass has to be filed when finished wear safety glasses and leather gloves. The tires came off of an old three wheeler for back make it look awesome. I used tote gote tires for front an old chrome steering wheel and an old plastic bucket seat. For bearings on the axel on back use the generic cooler bearings. If one goes out you can replace easy. My go kart can go on dirt and pavement. If you want a pic let me know. Good luck Steve

Golf cart parts are ready made steering with suspension for the go cart thing. Chain saw engines are great for go carts, but being two cycle, are a bit stinky when they run. They were used on the first racing go carts back in the early sixties. By putting one on each rear wheel, speeds of over 65mph were attained. Have fun, but keep it safe.

it doesnt matter what kind of load the engine can load because there will be gear's on the go kart unless you want to pull the cord and go flying.

I have a go-kart with a YZ 80 engine that i found in a junk yard and took it off aYz that had been run into a tree.The bike was prity messed up but the only thing wrong in the engine area was the chain was broken.It runs great and it goes through so much mud you can't beliave it the top speed is around 75 mph it a blast driving it. My dad had the frame made for me for my birth day by one of his friends it has 6 inches of travel in the rear and 5 inches in the front.I put the engine and every thing else in by my self it took me one full day to put in the engine by my self.

-- Stephen (, April 12, 2001.

Yes, I too have been heavily inspired by Junk Yard Wars. I decided to build a dual breast pump. I used a $19 Kmart ceiling fan for a motor. I used a belt drive to gear a jackshaft down to 60 rpm. The jackshaft runs a bell crank to drive a 1" piston with about 2" of travel. The end of the cylinder is sealed and has two ports for the tubing to hookup at. From there the tubes run to the breast cups. The cups are clear. It is neat to watch their nipples as the suction pulls them in and out. I did not know they could do that! Everyone has enjoyed testing the unit out. The fan motor has three speed setting to drive the nipples. It has been a great project and I hope it will last through years of testing. The only thing left is to make different size breast cups.

On a smaller scale, I built a go kart with PVC pipe, Honda Accord stater motor, and 4" wheels with pneumatic tires from a wagon. No welding and costs less than $350 total. Has been going for 1yr. with no major problems - other than worn tires.

Years ago I built a cart from a old lawnmower frame, just stretched it out 14 inches and put my old 125 Suzuki motor on it, it was a 1972 bike so there wasn’t the big power band that today’s bikes have. I had to lengthen the shift lever so I could shift it by hand, didn’t worry about a clutch. I just shoved it in first and the thing started spinning (even on black top). The only thing I do regret is I also didn’t worry about brakes! It made things hairy in the woods but an absolute blast in a hay field. I lowered the seat to the frame after the first test drive to get the center of gravity down. Used the lawn tractor tires that were on it, they worked fine. The cart would squall the tires on pavement in the first three gears. It was a blast (remember I was 20 and bullet proof) Good Luck

-- micah lynn (, October 26, 2001.

i wasn't inspired from junkyard wars or anything, but i have always wanted to put some sort of engine on a normal bike. My idea is to find some way of fixing the engine into the triangle of the frame, and have a chain going directly to the back wheel. I found a suffolk colt lawnmower in a junkyard, and the engine works, but it is a bit big for the frame of the bike. I was wondering if a chainsaw engine would work, and if that would fit in the bike. Please e-mail me with any suggestions or ideas that might work, or if anyone knows anyone who has been successful with a similar project please give me pictures. Thanks and good luck to everyone else put there trying to make anything. Chris

Hey! I love Junk Yard wars!! N-E ways I have a suggestion for your cart.. Me and my cuz recently spent alot of time getting a engine for our go ped we were making from scratch. We went to the Di in Utah and found a scooter, off subject.. The best motor that I think would work would be a snow blower or a edger (kinda the older ones) theyre not as bulky as a mower but can have quite a punch! SO enjoy have any more ideas about anything give me a e-mail..later

We race Micro Sprint Karts here every Friday night all summer long and they are exactly what you discribe. Micro versions of Outlaw sprint cars with 440cc snowmobile motors on them. Average speed on the 1/8th mile dirt track is 55+mph. For more info you can check out and if your ever in London, Ontario on a Friday night you know where the best racing action is!

-- Kart #15 (, March 26, 2002.

Yes. you should be able to get that much i have a small go cart with a 5hp briggs engine and a centerfugal clutch that will run in the mid 40's. i also too the governer out of it so im actually running about 7 hp. also consider your gear ratios. if you use a small gear on the engine and you want speed then use a small gear on the axel. but if you want more torque, use a small sprocket on the engine and a large sprocket on the axel.

-- Todd Myers (, March 27, 2002.

also, you can turbocharge smaller engines. there's a site somewhere where you can buy the products. i dont remember the name though. search for it on yahoo. if you need a clutch its best to either us a centerfugal (sp?) clutch or a torque converter. the 1st one is 1 speed and its pretty reliable and i think the torque converter can be a 2 speed. im not sure though

-- Todd Myers (, March 27, 2002.

40+ mph sounds decent for my first go kart. It might be hard for me to find a smaller turbo, so do you think a turbo from a car would work, or would it put too much stress on the engine? I think I might just find a motorcycle engine or some other engine that already has the gearing and clutch intact so I don't have to mess with it as much.

-- Pete (, March 30, 2002.

As some one who has built a couple off road karts, and as some one who is involved in mini baja racing i am not a big fan a chain saw motor karts. The small displacement makes the kart a real dog on the bottom end and if your a guy of any size it is just not enough power to get you around. I would recomend what i am using in my current project, a 337 rotax two stroke snowmobile motor. It is all aluminum and packs a 35hp punch in a package lighter then a 10hp briggs and straton. One thing to think of...the motor they run in midgit sprint car racing is a 250 rotax with a six speed. Though i would go with the senterfuge cluch and ctv transmition pulley from a snowmobile. And whats with all the concern over brakes, they only slow you down. Have fun and good luck.

-- Jon Speelman (, May 02, 2002.

here's an idea i've been working on for a couple day's now. Just to need to get the parts. Anyway, find an old sled somewhere, preferebly with bogiewheel suspension to reduce wear(I have a '76 Moto-Ski Spirit 250, similar to the Elan 250). Take the ski's off and instead mount wheels on. You'll have to do some measurements so you get it right. You don't want it tipping forward or have it's nose stuck in the air. Actually I got this idea from another guy. He took an old sled, couldn't remember what kind, that had a 16hp hirth in it, did the mod's mentioned here and he claims it will go just about anywhere. Even go's great on tar down the road! He claim's he was clocked at 80!

As far as a turbo-charger is concerned, find a small smog pump. It can be belt driven from the motor an act as a supercharger. here's a link for some more info arging.htm


-- Nate Huntley (, May 03, 2002.

another thing i forgot to mention, make sure it's a rubber track. A cleat track could be used but wouldn't work well on tar. It would also have a tendecy to dig dirt quite badly. just my thoughts

Well, If you want to build a go-kart, draw alot of pictures of what the frame could look like. Include the roll cage. Find some axles and bearings and stuff on ebay (really cheap), get an engine (I have an old Briggs and Stratton 9HP on my 2 seater off road buggy, and it flys at over 60MPH) and put a sprocket on the axel and jump in a glass of milk!

We fixed it and it ran pretty good, then out of no where it sounded like it wasnt gettin gas. we bought some new gaskets and stuff and put them on and it turns out that the wire that connects around the spark plug didnt fire. The magnet works fine, sparkplug is fine, so we figure thats what is wrong with it. if this has ever happend to any one, can you email me at and tell me how i can fix it. or tell me what you think is wrong, thanks.

i got an old riding lawn mower that had a 12 HP briggs on it. spending 4 months on it, extending the frame 12 inches, lowering the seat to the frame ( an 80 dollar racing bucket seat )built a roll cage, i brought the axle above the frame, ( a 1 in. diff. axle with large golf cart tires ). it lowered the cart to lust 2 in. off the ground. i completly rebuilt the front stearing solid. i coustomized the body with a ton of sheet metal, fiberglass and body filler. after finishing it, theres not anoyher one like it. dont think i forgot about the motor, i put an old honda motorcycle motor ( cb 350 ) off an old crouser. i got it out of a closed down junk yard. it odviously hasent been run for over 15 years. it had no carberators on it, and no balis resister for the charging system. the coils were water loged and two of the wires were broke. i dryed them out, and made then temporarly work. i hooked everything up to a 12 volt car batery, sprayed some starting fluid into the cylinders. the first time i tryed starting it, it started and ran for only a few seconds ( no carberators ). now i new the motor was, to get the motor running and looking good, i got a carberator and intake manifold off of an old 4 cylinder car (1.6 leter),made an intake manifold to fit my motor (my motor is a 4 cylinder), bought a universal fuel pump, and hooked everything together. then i had the ignition problem. its a 4 cylinder with two coils (two cylinders per coil), and it has points ignition. so i got 4 coils (1 coil per cylinder) desined for older chevy v8's with points ignition. i made sure they had copasitators and resisters built in them, hooked them up to the points on the motor (2 coils to 1 point) and they work like a charm. the charging system would have cost me 400+ dollars to get working, so insted, i hooked a pully to where the generator was.then i put a crome "1 wire" alternator on the motor with custom made mounts, it works great. the motor had straight exaust (no muffler system) with crome pipes. they were rusted to hell from being so old, but steel wool and wire brushes cleaned them and the motor up like new. i joined all 4 pipes together into 1-2 1/4 inch pipe, and custom made an exaust pipe to the back and put a regular car muffler on it (it has to be quiet to drive on the streets in buffalo new york). to bring the power from the motor to the rear axle i hookeda jack shaft up close to the motor, so the chain went from the motor to the jack shaft then the jack shaft to the rear axle. thes made changing the gears very easy. id say the hardest part of making this was keeping everything above the frame (exaust, drive chain,ect.),but it was well worth it, considering it go's from 0 to 60 MPH in less then 6 seconds, and with it being a 5 speed, it tops out at 140 MPH (now can you see why i redid my front end).and being 2 inches off the ground, it handles better than any car ive been in. and, all in all, it all cost me less than 400 dollars. i hope telling you's about my project will help give you ideas on some of the thing that you can do.

hello, some of you may be interested to know that i have built a bicycle with a small engine on it. the total cost was about Aus$50 and it gets up to about 50-60Kph (30-36Mph) you can have a look at it here: enjoy.

-- Kendal Boughton (, November 19, 2002.

oh and jason, if you make an 'L' shaped bracket to mount the engine on its side you wont need the gears, it should run fine if its a two-stroke and the float chamber is pointing down. (dont do it with a 4-stroke V- shaft)

-- Kendal Boughton (, November 21, 2002.

to the above....yae i know if i had a 2 stroke it wouldnt matter but its a 4 hp 4stroke and im trying to find some kind of gear to go on it to convert from the vertical shaft to a horizontal shaft under the body of the lawn mower to conceal it better...i know they make something but i dont know where to find it

First of all, I need a clutch or a way to drive, because I dont want to start and go. Also, I would like to find another motor of same size, again it is an old stihil chainsaw one of the bigger models, but i dont know the model #. If there is any help that anyone could give me I would really apperciate it.

-- gull (, March 07, 2003.

hi i have just built a go-kart from 1" box section. i had no help and it was fairly easy. i have the engine from a 1970's simson motorbike. it is 50cc with 5 gears. the frame was welded together all by myself. i am only sixteen and this was only my second time arc welding(the thing will probably fall apart !!!). the accelerator is controlled by a lever on your right hand side and a hand brake on the left. i have not used the cluch i just ram it into gear and fly off !!!. the kick start has been taken off so the cart has to be bump started. the main problem i had was getting the rear sprocket for the chain central does anyone know how i can get it better for the next one i build ???

-- martin (, March 09, 2003.

To quote an erlier post "What is up with you guys and chainsaws". Chain saws are EXTERMELY weak. An erlier post said it has to have power to go thru logs, but they only need to chip a quarter inch path. I strongly reccomend against the usage of chainsaws. Your kid will be very sad when his cart goes 3mph. I reccomend going to a used mower shop. There you can score a 5hp briggs for like $50 (Very reliable engine, i got one from 1982". This, combined with a tourqe converter, can have him tearing around at 40+. All that crap about 60mph carts is bull. You simply cannot go that fast without a fast bike or a car. You NEVER EVER want to go that fast in a cart. A car maybe, but a cart thats bolted together with you 4 inches from the pavement, never in a cart.

PS: You can build a electric cart. This means 1-No $40 clutches 2-No $140 frame 3-No Throttle 4-No engine hassles With electric- just plug it in overnight and cruise around with 6hp for about 2 hours in the marrow. Low tourqe means you can reinforce PVC pipe and make a frame out of it! No kidding, PVC! (I have one, definity a flat land cruiser)

This is a question. I have a 12.5 HP riding lawnmower engine. It has a vertical shaft and I was wondering how i could use this vertical shaft to power an axle--obviously horizontal-- could I use a belt like the lawnmower did and snake it into a figure eight type shape. And when doing this where can i find a Cent. clutch that can take that many horsesand how would i hook it to this clutch. Im only 15 and dont no a whole lot about engines or clutches and gearing. All i know is that the gearing on the back axle of the lawnmower isn't utalicinz full power of the engine if someone could please email me some of this stuff it would be greatly appreciated.

ok heres one for those that want to build a frame with out welding its really easy what u do is get your pvc pipe then insert into it a wooden dowel inside of it to give it more strengh ok lay out your pvc and make all your cuts then cut the dowels to match use red hot pvc glue to put it together should hold up to any thing u want to do well on the subject of carts i just built a 3 wheeled trike from a old 3 wheeled golf cart put a moped front end on it giving it a nice rake made some custom handle bars and came out nicely it will go roughly 25 30 mph on flat land but still able to climb a hill at a good clip so i hope this helps all of you good luck

I have been buildiing karts for many years all from scratch. Who ever said that a chainsaw engine would be suitable are obviously not very experineced and are not really in tune with what you are making. If you defernately want a horizontal shaft engine you are going to cause youself problems with gearing. My suggestion is to get an old ride on mower, and use to dif and then belt drive , and obvioisly the gearbox. This way you will have good acceration in low gears and a good top speed, easily 40mph. However these have vertical shafted engines. All you need to do is put a larger diameter, pulley on the engine and your kart will go like a bomb. You should be able to pick one up for abpve £50-100. Check to dif and the engine before purchase though. Good luck and happy building. If you have any problems email me.

I first of all want to say that money IS a problem. I would like to either find the parts or be able to jury rig them pretty easily. The engine that we put on the go-kart had a messed up carburator, so we replaced it with a 2HP Briggs and Stratton carburator (is this a problem) the engine still runs fine. We are in the process of looking for or maybe even buying a centrifugal clutch the previous one which was on the 2HP does not fit. If anyone could give me a suggestion i would really appreciate it.

i have been trying to research building a cart for a long time and have came up with some good info. for those of you who have a vertical shaft engine, go to ebay and get a transaxle from an old lawnmower. like a spicer or peerless. heres a link to one of the many... ViewItem&item=2338995537&category=20544

also, to find your top speed:

rpm of axle = engines rpm/gear ratio (ie 6:1 would be 6) 600 = 3600rpm/6

distance=rpm axle * circumference of tire (ie 10inches*3.14=31.4) 18840inches= 600*31.4inches

miles per hour=distance/1056 17.84mph=18840inches/1056

I live in Long Island of New York so i dont know where i would go. Do they allow you to seach through there looking for old things or do people some how sneak in.

hey ryan nick... dunt buy that mini- chopper. It is a watse of money and im sure you would be dissapointed with the results. It would be cheaper to build your own and use something like a 5hp horizontal shaft engine to power it. You can find a good used 5hp engine for about 150 and if you use a centrifugal clutch that only cost 30. Chain would cost about 10, throttle control 10, and a frame can be bought locally, or built. i would not recommend ordering offline. if you need ideas for your frame email me. I have built 2 minibikes working on a third which will be a chopper, and working on a hovercraft. The first minibike i built uses a 3.5 tecumseh and will go about 30.

I used a Johndeer 440 water cooled in My offroad gocart. At 60 mph the cart is still fishtailing. It`s a bast,butt I have low end. Gears are the way to go.

The 440 is fun but I just picked up a Huricane 1000 ( Honda ) Thats what is going in my old frame. The speedometer goes to 185 mph ( we shall see )

I have a 3hp Briggs and stratten on a three-wheel go-cart thea i built my self. I am only 14 years old so i had to use stuff I hade laying around. It startedout as a down hill cart. the front was off a bike and i welded it to a frame mate out off one inch square tube all welded to gether by just me. in the back was two 12 inch scotter wheels. i then got a go-cart motor fron a flea market at the fair. i used one-wheel drive. i left the right wheel alone while i used 2 bronze sleeve bearings which work OK. iused a belt drive because i hate chains. the cluch was a pulley that would ajusting the tension on the belt with a hand lever. the motor runs like a champ. in the country, it ran about 40 MPH! Remember that was with a 3 HP motor. now in has a real cluch and the wheelthat was on the back is now on the front because i hit a stop sign and it mangled my wheel. i also hah to move the brakes down. in the back are wider 10 inch tires.

I am making a go cart with the chainsaw engine. The problem is I don't know how to make the gears. I would like to be able to start it on neutral then accelerate.
