Secret Tecumseh Performance Mod | One Bolt On = WAY More Power!
ฝัง
- เผยแพร่เมื่อ 6 ต.ค. 2019
- We take our Manco Dingo powered by a 6 horsepower Tecumseh OHV engine out to our favorite ATV park for a thrash! We planned on doing some stock baseline performance testing, then swapping the engine to a stage 3 Predator 212cc engine. After realizing that we didn't have the proper tools to perform the swap, we decided to use the same 6 horse Tecumseh engine, but swap the stock carburetor out for a 22mm Mikuni carburetor. This fixed the performance issues caused by the stock carburetor, bypassed the governor, and flowed better than the stock carb. All of this gave the little Manco Dingo go kart a HUGE performance boost!
Thanks for Watching!

I had a Manco Red Fox when I was kid. My dad and I hopped it up by stiffer clutch springs in the torque converter, header pipe and by passing the governor. It would legitimately do 57 mph on the road.
I’m getting a yerf dog 3200 on the 6th of July aka 2 days from now, what should I do to get it to go above 55?
" we have been to that bridge that is where that kid almost drove off" that kid is me hahaha
Ha Lol😂
Hahahahah you scared the crap out of us that day.
@CarsandCameras you should do a FUEL INJECTED GO-KART or 2-Stroke kart🤔
Hahaha 😅
Atta boy! In the words of the great Larry Enticer, "Just gonna send it!"
Looks like a blast. I've rebuilt and modified nearly 1000 Tecumseh Carbs and have a love for them. They will however always have a dead spot when used in a go cart. They were designed to keep a steady rpm and do a fantastic job at that. If you want to slow or even stop oil blow by, don't use multi viscosity oils: sae 30 only.
It says on mine to use 5w-30 in the winter under 32 degrees and SAE 30 otherwise, but it was on a snow blower and I want to use it on a bike. I was thinking of running a good 10w-40 with a dash of racing ZDDP from Lucas oil. Is that a bad idea? Should I just run the standard 30 and some ZDDP?
I need to dismantle and clean the carb, then mount the engine, then built an exhaust before I decided on oil anyhow. I think I will go the 10w-40 route with ZDDP unless there's some big issue... Maybe I'll get back to you and let ya know if I'm blowing oil haha
@@greenbassboosts8872 Only run straight sae 30. Multiviscosity oils are meant for water cooled engines. The higher temps of air cooled engines will break the viscosity modifiers down and they will act as simple 10 weight oil.
@@sixtyfiveford okay good to know. I'll pick up some straight 30
"14 seconds on a carburetor swap" annnnd a governor bypass.
Ted Fryman annnnd a longer runner
@@haydenmadigan8186 I was just about to mention that. Few people realize what a difference a change in the sonic resonance tuning of intake or exhaust manifolds can do. That longer runner most likely gave that engine's low-end torque a "shot in the arm" it badly needed to help that [likely[ heavy cart perform well off the mark. Imagine what it'd do with the addition of a tuned header...!
@@haydenmadigan8186 Longer runners the same effect high-rise intake manifolds have on V-8s. Stock Tecumseh carbs suck, Mikunis are da bomb! Great video, thanks!
Usually a stepped straight header is about the best for these engines as well as a 30 to 45 degree intake vs the 2 90 degree straight down intake that style intake is very good for lowend torque the exhaust heats that portion up resulting in more of a gas to oxygen mix then a liquid to oxygen mix if that makes any sense 🤣 the 245 cam in one with a decent carburetor a straight header will suprise one who doesn't like them.
Kylee Bates yep that's very good advice for almost any engine, i also like to achieve roughly the same displacement as the engine in volume on both the intake manifold and the velocity stack (or intake tract) and decent length header, I did some math for a stock cam gx200 tuned for 3600rpm and came up with a total length of 550mm 1" stepped at mid point to 1.25" and 180mm of 1.5" on end, My clutch engages really hard now with that setup
The "intake pipe" you guys put on could have brought up low end torque too.
You know, that janky dual manifold system gives you more torque!! That's why it threw rooster tails! I love how old school this video was, just you guys havin' fun on a go kart, trying to make it go fast without dumping too much money and time into it! Keep it up!
My Tecumsee 's always ran great !.,..ah...I miss those days ! Glad you had a great Mini-Mayhem !!
I would love to see you guys build up one of these tecumseh engines, I think they have a lot of potential
And I got three of them just setting around . Now they have become " Keepers ".
I'd love to see them build up the briggs intek they had on the mower. Ive got one and it's a haus when clean and all. I have mine on a vertical shaft motorcycle build.
No they dont they are junk I had one same one as them spit a rod... the old ones 70s and back are built like brick shithouses but newer ones are scrap you over rev em it's not if it's when it spits a rod
I got one with a 356 cam in one. And a bullet rod
A decent amount of guys race those motors around my area
Busco should pay you guys, looks like so much fun!
Shaky Hand Pictures You’ve got that right!!!
8:43 pure joy at its finest
Sometimes simple = better! You guys are gonna LOVE the upcoming Mini Mayhem videos!!
so true love you guys
What neck brace or hans device are you wearing in this video?
What size main jet did you use in the mikuni 22 carb when you swapped it on to the tecumseh?
9:54 "just some good ol' boys..."
Beats all ya ever saw
Been in trouble with the law
Since the day they was born.
For the intro: you really earn it guys and you doing great work! The first video I saw about messing around with gokarts, crosskarts and all kind of mini-fun-stuff with tires was: 10 reasons why to buy a used kart! You are a great inspiration!
Ike's laugh, in the background, during that test after the new carb, was the best.
I'd love to see you guys mod the Dingo. First thing that I did to mine was lengthen the frame 6 inches and put a molded seat into it. Followed by a 420cc engine of course🤪
Great to see you guys out at Busco last Saturday, thanks for taking time to talk with us. Gonna work on having something to ride at the next Mini Mayhem. Btw John I really enjoyed talking with your Mom she is super cool! Maybe you should build something for her! :)
Nice to meet you, too! I had fun just watching everyone else have fun, but I'm not gonna lie...I would love a mini bike!
Had a go kart like this with a Honda motor; absolutely enjoyed every second of it 👍👏🏼 good video guys!
The Tecumseh motors can by drastically improved with stock parts. Just mod the carb for crazy amounts of air and fuel. But the performance parts that will take the stress don't really exist. I've seen my dad do it several times and they run like crazy until it blows up, and I mean blow up. If you stay moving you will probably not get hit with hot oil!
Damn😢😂
Unfortunately true. Performance parts for Tecumseh engines are practically nonexistent which is a real shame. The connecting rods are weak on these engines.
If you put a pipe on it you can actually bolt the carb right to the factory intake manifold , I have an 11hp tecumseh here with a vm-22 and a straight pipe and it works fantastic . I also have a Manco dingo cart so these videos are great .
Had a Manco Dingo since I was a kid, still have it. Gotta put a new torque converter in it but just like you guys experienced, it handles better than average. I've had a few different motors on it, be cautious as the frame can twist, I was running a 16 horse 2 stroke sled engine in it and bent the frame where the bearings hold the rear axle. It's a strong enough design for every day use, but was intended for a 5-6 horse motor. Keep that in mind when going up in horsepower...I know you guys lol
Y’all are my heroes and are both so humble. It’s awesome to show viewers you can have fun and be safe at the same time.
8:43 THE LAUGH "AHAGGAHHH"🤣🤣🤣
Yes! Finally a Tecumseh build!
Please do a full build on the Tecumseh.Would love to see the outcome.
Can't stop smiling watching this........ nice break from the garage.... true!
I'm actually doing a Tecumseh build. I have a stock max speed on a Manco Dingo of 26mph. I've only really done the Carburetor so far. I've completely stripped the carb, Removed all crap and junk from inside. I've bent the valve arm some to allow the carb to open up fully! There is also a little screw that holds the butterfly valve to the post that rotates inside the carb inlet. There was about 1/8th of an inch of screw sticking out the otherside, I have completely shaved it down smooth flush to the valve post so it should flow air a little more better. I'm excited to see how it all performs so far. Next is the head. Gonna do the Playdough trick and see how much I can safely mill off. I'm expecting a 50+mph run with no performance parts. Just my own tweeks and mods. Definitely going to add what you guys did here and adapter for the airfilter!
The word I thought of when I saw this is
BUMPY
Tecumseh engines were manufactured in Murray, Kentucky !!!! I drove for Paschal Truck Lines(...PTL...) and that trucking company and Tecumseh engines were the biggest employers in Murray !!!! It is the home of Murray State University, and they have a nationally recognized college baseball team there too....Amen !!!!
NR Racing, ARC Racing, OMB Warehouse, they might have some parts for the tecumseh, but if not they could open you up to a whole new world of racing.
If you rebuild it for off-road, I highly recommend rubber or polyurethane bushing under the seat. It absorbs the rough terrain and it worked wonders on my Manco!
Can’t wait to see more!
JB
Wow that thing was flying until Ike decided to go mud bogging, LOL
Tecumseh pull starts are such a pain, good vid though guys! Y’all are killing the game. I need some power mods on my QT50
The longer intake runner might have been part of the increase as well. The intake is supposed to be a certain size percentage of the engine volume and factory rarely is.
Im super happy to see someone else have the same problems i always had with my tecumseh, tons of power, until you hit a bump, then stumble.
16driver16 that went away with the mikuni swap. That’s how you fix yours also!!
@@noonecareswhenalltheydo if i still had it, though i had very little mechanical knowledge when i did, but now a kid could look it up and watch this video and bam
Good video! I laughed my a** off when Ike said "I got lost". I had a great time at mini mayhem. I was the guy with the white Van and the klr that barely works.
These editing skills are getting really really good ! Can't wait to see more of these engine builds
Man il be really looking forward to see a tecumseh build. Great vid. Keep up the awesome work
You guys had a good time out in the boonies and that carb change sure made a surprising difference and it showed on your faces ! top notch stuff !!
LOl i love how it pulls a wheel now on the start.
Look up OMB WAREHOUSE they have a billet rod for that Tecumseh
OMB has lots of good stuff
@@StansWorld They have a lot more than gopowersports, they have briggs performance parts too.
I ain’t gonna lie, that roll cage seems janky as you know what. Thanks for the video guys.
I feel like mini Mayham is literally go cart cruising the coast
I've been to the Mississippi side of cruising the coast.!!!
I’m going this weekend
Can't wait for Tecumseh engine make over that will be awesome!! Old Tecumseh motors are tough!! Keep up with the quality Videos guys as I always say you guys are teaching the younger generation that they can do things with the hands if they put there minds to it. Faithful Subscriber forever From Southeast Missouri. CAR's and CAMERA'S ROCK!!!
I just bought a maco baja 200, which is almost exactly what u guys have in the video. The 5hp Briggs and stratton engine was seized up. I found a tecumseh 6hp engine used for 40 dollars. Its starts everytime on the first pull. I will end up doing what u guys have done in this video. I paid 200 for the dingo and 40 for the engine. For less than 250 in it feel I'm doing pretty good.
The moment Ike burried the cart in the mud I could not stop laughing!
Great video guys and I can't believe Ike just dove right off in that mud puddle like that lol
Ikes maniacal laughter made that! 8:43
You know those dudes are railing on it 10/10ths seeing it ping ping between its 4 wheels. That seat cushion would be worth its weight in gold. What a cool little kart.
We have a couple, they're torquey little Bastards. We have a trail bike with a 6 on it and it's quick as hell and does almost 40. I took a compressor and tank that someone gave me and put a Tecumseh 3.5 on it and it pulls it just fine and it had an 6.5 horsepower on it before that sounded like it was working hard to pump the pressure up. That little engine looks insanely small on the whole compressor setup. Surprisingly powerful engines.
never seen a 1 second mud dump! Perfect! I would be scared of that go-cart. Cool vid!
Gotta love those Chinese pvc roll cages! Life savers, those are!
Awesome
Look like tons of fun as usual
Lol when John was goin around the track after the carb “ ow ow aaa ow ow ah “ hahahah 😂 man I can’t wait for mini mayhem spring 2020 I have to go with my mini !
Hey, you guys rock! Just got a dingo gold line and a brand new Honda gx390 with a 40 series torque converter. Hoping to have it alive this weekend!
Thanks, guys. That engine is impressive for what were junk engines when new. I had one on a mini bike took it off and put a real old 2 1/2 briggs on it and never looked back.
They seem to run good for a long time on snowblowers, lawn mowers, not bad engines I think
i've never thought much of tecumseh engines. they always run kinda funny, and never seemed to have the power of a briggs. and to think, it was the crappy carbs all along. i'll have to look at them a little differently from now on.
I did give a couple of tips on the comment on the last video of this kart with the tecumseh ohh60 6.5hp engine. I was thinking the 22mm carb would be to big if I remember correctly the intake valve is 23mm and the exhaust valve is 19mm it's been a while an my calibers battery is dead and I dont have a mechanical one. The valves can be changed but they are a larger valve stem. The 245 dyno cam is pretty good cam for these engines I do recommend upgrading valve springs a clone or Honda style spring is slightly larger in diameter so if those being ylused the spring pockets will have to be cut. Oh and note the crank does not have roller bearings like a 196, 212 and so on. They have a bushing style bearing same as the rod and wrist pin. So they will need to be checked. The 5hp ohh50 series cylinder head is a smaller combustion it will help the 6.0 ohh60 engine being a bigger bore. I'll have to get back with you on the bore sizes. Also the blocks of the tecumseh ohh50-65 series engines arent braced well from the casting they designed. So I would definitely recommend having someone tig weld braces on the block very costly but well worth it when the block can handle what you throw at it. They are a very interesting engine to not only run and it run well but to work on. They are very bad for valve lash if not wanting to start...they was based for road coarse racing the f200 class and they was definitely designed for racing and not longevity. I'll see what all other info I can find I wrote down on these engines.
That thing is a BEAST
Those performance parts sure make a huge difference. I wish they were cheaper to bring up to Canada.
13:10 this go kart is stuck, just assume total loss and get a new one. Also you should make a go kart then at the next event hide it, and have a scavenger hunt for it.. whoever finds it has a great day with their new go kart!
Man i miss busco already. That was a good race at the track between the pit bike and and dingo
Love the video keep up the good work and thank u for taking us along for the ride
Keep up that GREAT work! You guys are amazing! I subscribed!
Bring back the drift mower pls
Also, that roll cage is looking incredibly flimsy
AIO inc. that roll cage aint shit bet its gonna break soon
Made about 10% weaker than neck bones...
What roll cage ?
I have a Dingo and trust me, the roll cage does its job just fine. Don't ask me how I know.
This thing has a beefy roll cage compared to they're green so called cheap heap
Please say "Techums-ey" lol. Im from michigan with the namesake city Techumseh. Thats how its said. Otherwise keep on keeping on! Love your stuff!
Run a line from the crank case vent down to the oil cap reservoir spot. It would eliminate the issue of losing oil. Maybe add a filter from the crank case down.
I don't know where you purchased this go kart but this one is at the very least perfectly identical to the one that I had as a kid. I regret selling it back in 2016. I think this one could have been mine based on how complete it is. So much fun!
You do see people helping each other in every single Motorsports I’ve ever been involved in although it’s awesome you said it
Maybe next time before going out, use your phone to find where you started from. Thanks for the exciting vid. Made my day
4 bolts seized bolts change the course of a whole build? Yep been there, Actually refreshing to see the diy performance on here again
The Manco Dingo is a awesome offroad trail buggy I have grown up with Manco Dingo buggys and Honda Odyssey buggys my whole life been all over
good vid. build the tecumseh, it's screaming for it. i think ike may have coined a new phrase after having hurriedly devised a way to install the mikuni on the tecumseh, "Jankee Ingenuity".
this is my favorite video and type of content that's been on this channel in a long time
I had a tecumseh engine in my lawn tractor. Brilliant little engine!
It looks like you guys were having a blast another great video keep up the good work
Whoa whoa whoa. What's that thing in the background?...
MrLendermanGaming test driving the cross kart while there.
If you're referring to the white thing when John is talking about the Tecumseh never being off that cart they're working on ~@5:30-ish, that's the X-Kart they've been working on. Check past videos.
I thought so but potato phone couldn't make the video out.clear enough to tell. Man that thing has a sweet stance!
@@MrLendermanGaming It could use some bigger tires, but they're already planning to do just that.
Man that looks like fun!!! Had the whole place to yourself!!!
ive always wanted to rebuild my tecumseh 6.5hp but parts and performance parts are the only problem but awesome vid boys as always itl be fine
Keep Good work up guys!
When do you guys EVER rebuild something to stock ...hmmm Not
Go crazy with it ...as usual.
Looks like fun!
Luv yals vids! Great job
Every Tecumseh engine I ever tinkered with had a crappy carb on it. Must be a Tecumseh thing.
Breaking conrods is a Tecumseh thing
Michele beck they just don’t like being beat on.
@@michelebeck4311 sticking valves/breaking lifter bores is a Briggs thing
OMG. My back hurts. Lol
Cool park, awesome video!
9:56 Jon did all that for a slower time 😅😂
Next time you come to that bridge stay to the right, drive down about another 400 feet and take a left and it will bring you back out behind the first pond on left side coming in the park entrance 😉
Ha Lol🤣
I would have been very interested to see how you guys hooked up the new carburetor with the throttle
Mud dive was awesome
Cool vid. Looked like fun
The Dingus go cart did pretty good
for your health dr brule :)
The garage stuff is great, but it's good to see you guys taking the machines out for a thrash, and not in a sketchy 'I hope the cops don't show up' kinda way!
it'd be good to see that tecumseh built. a lot of people start out with an old briggs or tecumseh and it would be good to get away from chondas for a while.
In the sixties Rupp made minibikes that had Tecumseh engines with Dellorto motorcycle carbs. They were fast.
I like the video even tho I wasn't happy. That cross kart sitting there and no vid. What the heck. Lol lol
Where was Isaac at the end? I could hear him talking but couldn't see him. Oh there he is. I couldn't see him for all the dirt on his face!
Up next, shock absorbers lol. Nice video guys
Let’s go more vids yesss
John all the way around the track
"Eeee, ooooh, ooow, eeee, ooooh oooo, ouch!"
Hey guys i love your work with these machines, say hello to Brazil!
Mud diving on a go-cart epic.
We all heard you back off on the jump for your timed lap “you chicken 🤣”
Of course he did !!? 🤬🥳😎
