Hey Mustie. I know you get it a lot, but I want to thank you for giving me the confidence to rip a carb apart. Mother in Law gave us a $1000 snowblower she used once as a house warming gift and said it wouldn't run. It'd run rough at idle and any throttle would kill it, and it leaked fuel like no other. Tore it apart, cleaned it up (filthy!) and now she runs a treat and is ready for winter. Turns out she'd used 2 stroke fuel in a 4 stroke motor. Really gummed it up horribly. Appreciate every video you put out.
Multi-Cylinder Two strokes ALSO have crank seals between each cylinder- so the ends might still seal vacuum leaks, but they will TRADE the intake charge between the two- so one runs lean and one runs rich
I grew up with 2 strokes and am a big fan. But they have to be right on the money. One little air leak in anything and you could destroy the engine. That was the demise of many 2 stroke outboard marine engines back in the day. Cheers!
Most time the seal around clutch and pull starter seal drys out and it common on old snowmobile engines and its usually there demise because people don't realize and then over heats engine blows up I would even just because of age replace those seals there not expensive but would be right thing to do it seam like go canadate for some love also u could get a lighter spring for clutch to close earlier I like to see u do something like this up I did something similar years ago on a gas on with a 250cc and I made a expansion pipe from old dirt bike fresh .10 over piston up compression and add flat slide carb and some clutch fullarey and it was so fun u could get it to drift with stock tires love to have another one and build it liquid cooled and a twin or a old quad motor.
Honestly I just eliminate the oil jug and premix worked on so many failed injected motors to learn if I own it it got eliminated for reliability and it be cool project to do something cool with and I would put crank seals on either side because for the age sure there leaking and motor seam like good canadate for some love
@@just-in-time6069 Can those two seals be replaced from the exterior or does the side cover halve to be removed. Im thinking you can pop them out and tap in new ones without going inside the engine but don't remember.

Love the stash pile! I bought a go cart at a sale 12 years ago. It had a snowmobile engine on it. At that time I didn't weld and there were many issues. That thing was fast and it had a small gas tank with it and a kill switch. Kill switch came in handy because as i flew through my pasture and all i could see i was going to wipe out in a tree. The steering wasn't much to talk about because it would stick one way or the other. The way they had a battery in it, it wouldn't come out. It turned out to be a waste of money. I only paid 100 bucks. When I moved i left it and apparently the new owner played with it.
Now that you weld... I've converted steering to the mini tie rod looking things some Asian autos use as sway bar end connectors. Shopped around until I found a $20 set on Ebay My Snapper rider has SO much better steering feel now that the half assed rod/bushings are GONE (eliminated that 'stick one way or the other' as well) Just limit your heat input close to the end as they are plastic inside the steel end...

The issue seems to be on the CVT the rear one isn't reducing to increase the wheel speed . I think the belt is to slack and not putting enough tension on the rear CVT to make it work correctly
I think 50hp is spot on as I had a couple air cooled 440s over the years and they were around there, this video inspires me because I have a 1990 Artic Cat Prowler with a Suzuki made liquid cooled 440 sitting in my driveway that i've been considering swapping into a golf cart. Supposedly it makes 65hp, and my brother just got an electric golf cart for the campground so it would be amazing to be able to run circles around him 😆 Anyway, thanks for the great videos as always *Mustie1*
I think you're probably right - I'm not overly familiar with Yamapops (sorry - Yamahas lol!), but I know Polaris' 440s were anywhere between 40-60hp (around 60hp being the XCF440) depending on the year. To the best of my knowledge, the early 2000s Arctic Cat Z440s put out the most horsepower for a 440 at around 65hp. That said, I'm not sure I would trust a fan-cooled motor in a golf cart - especially when the temperatures outside are above 10℃ (50℉). I think your idea of using a liquid would be really cool if you could set up the clutches properly and its rear-end had decent gearing.
Hey Mustie, that looked like it would go OK if it could rev out. I say that because the belt never really got to climb the front pulley and raise itself to the highest ratio it could.
The centrifugal drive clutch is not closing enough. If you take the outside clutch cover off there are weights inside that close the clutch as rpm’s increase. Adding small weights to the existing weights will close the clutch more.
Hi mate, No:1 I would get rid of the fire starter fuel filter. I look forward to seeing what you have next each week, being disabled in bed 22hrs a day gets mighty boring lol.

I used to have two of these early 80s sleds and they were both 80-90psi when cold, I seem to recall they are only 6:1 compression ratio or something similar so not going to get massive compression out of it. 40 years old so crank seal refresh would be the first place i'd also check before trying to dial in the carb, which was also suspect. When you were giving it full throttle the crank side cvt rotor wasnt fully moving the belt up to the top either so gearing / belt system would also need sorting out. Shame it wasn't a simple fix as the sleds were rapid, Yamaha racing had tuned ones of these they used for competition sledding which put out over 80hp at the time
That era of snowmobile engine was when they were trying to get as much hp as possible out of as small and light weight an engine and not too worried about idle or low rpm running and never longivity. 40hp was huge back then for that size engine. I mean brand new they ran OK at idle and low rpm, but when you rode one you found out right away what the ultimate mode was: WOT. The guys who bought them used them to go from bar to bar in the boonies and they did a lot of drinking along the way. And rest assured there was plenty of booze stashed onboard for the inevitable breakdown out in the middle of nowhere. I worked in an auto parts store back then and the stories I heard about breaking down out in the woods and spending the night out there were just unreal. Most guys I knew went every weekend and spent half the time driving their trucks from town to town in search of parts. So, I believe you had that thing running pretty good for what it was ever designed for. They were as "peaky" as a 250 Elsinore. Thanks for screwing around with it, now I remember why I never got into the sport. ben/ michigan
In the 70's people snowmobiling past my bedroom all winter long, 'till the wee hours was the norm. Dozens, if not hundreds of sleds would shoot up the powerlines a few hundred feet away, every night. Now a few rides a year is possible, but 08/09 was the last for a "season" of riding...
About 27 minutes in, music to my soul! I used to have a Yamaha RD400 or 4. This one sounds just like it. I'd be surprised if Yamaha didn't use some RD400 designs on this engine. steve
Hi Darren, I sent you an email already via the address you have listed, but just in case that address is kaput, I wanted to let you that I have something I'd like to donate to you as a future "will it run" candidate, from down here in Southwest NH. I don't want to give any details here, but will say that it's small and powered by a two-stroke engine. I stumbled across one of your videos about 6 years ago and have been a big fan ever since, thank you for the awesome content!
Had a Yamaha 440 snowmobile, and man, that thing was FAST! I had my son ride it into my yard. He cracked the throttle and got scared. He bailed, and it ended up wadded up in the neighbors fence. 😳 Son was fine, and the machine survived to live many more snowfalls.
Your patience always amazes me. Id have driven that thing off a cliff about half way through your video, lol. Thanks for another fun video. Long time subscriber here.
A friend of ours built one similar (but my cousin and I didn't know), anyway one summer day Dave and I were outside and I said that I could hear a snowmobile. Finally Dave heard it and it was coming closer, then Steve showed up in a golf cart. I asked Steve about it later , he said it worked great until his friend lost control and hit a tree at the side of his driveway. he used a rotax 340,I think.
Pop those two joined engines in this thing and lets see what she'll really do lol another great video can't wait to see what comes next Sunday thx Mustie
Snowmobiles are 'tuned' to run in COLD environments. This means the carburetor is rich to compensate for dense air. Hence, To run in warmer/thinner air, the carb. needs to be leaned out. (both high-speed and low-speed jets) BTW: I am pretty sure that adjustment on the top is IDLE-AIR screw. (clockwise is RICHER at idle)
I love these videos and it's my Sunday morning ritual to get breakfast and watch Mustie1. I've got to say, the ones were you don't own the project are the least satisfying to watch. They feel unfinished. Even though some of your projects like that Econoline have been going for years with very little progress, there is still hope for their completion. When you pass them back to their owner with a list of problems it's less satisfying.
An air cooled engine designed for use on snow when it's cold out is going to get too hot in warmer weather so it probably isn't ideal for a golf cart. It might have been worn out when it was installed. Even a worn out 440 should have plenty of power to run that cart. Another thing I noticed is that the belt was running on the bottom of clutch on the engine and the top on the drive end which would be the slowest speed. The outer half of the clutch appeared to be moving in but the belt never went further out. Maybe the engine clutch was designed for a wider belt than the golf cart drive uses. Some of the older clutches could be shimmed to close them up. There needs to be a link to keep the distance between the engine and the drive constant to keep the belt tight for the system to function properly.
I love when you go browsing through your junk looking for brackets and stuff. It makes me feel less anxious about the crap I have piled in every corner of my buildings. Thanks for that. My son drops by looking for stuff and I can see on his face he's thinking about the mess he's gonna have to deal with when I croak. lol
Could the hole in the float bowl nut be for draining the float bowl slowly? Like a banjo bolt. Also - a thin sheet of aluminium could be added to curve around the mudguard, and stop the pullstart lead digging in.
The back hole was throttle cable hook up . The one it was using was for oiler cable to the two stroke tank. But it's working so guess doesn't matter much. Great work brother. Oh and that intake can either put plastic pipe inside to stiffen for a hose clamp. Also could just epoxy together because can just spin whole tube to put filter where u want it.
I have an early 90s Club Car Carryall with an anemic 9hp Kawasaki engine in it. It runs fine but is gutless. Now this has me thinking of a motorcycle, or snowmobile engine swap!
LOL I have never seen a vehicle rev so hard and go so slow. Good job 👍 PS I don’t think that front CVT pulley is working correctly, it’s not closing up far enough to give you a higher gear ratio. Yep crank seals for sure I would say.
I'm suspecting the clutch also, maybe Mustie smoked it with the burn out test against the forklift, would add up to the problems with the seals and fuel mixture... 👍
Actually, it's probably the secondary clutch causing the problem. If I remember correctly, Darren said that the secondary clutch is the one which came with the golf cart. If you look at the drive belt, it seems to be a perfect fit for the secondary clutch and when he fully revs the motor there is still a gap between the belt and the primary clutch. The issue is the primary clutch can't close enough to grip the belt properly and I doubt you could adjust it enough for this belt. My guess is the snowmobile the engine came out of has a wider secondary clutch (and thus, a wider belt) than the golf cart's and there's probably a good chance the snowmobile's secondary clutch wouldn't fit on the golf cart.
Good job investigating! I can't believe no one blows off or cleans these carts before working on them. You had a pine needle trying to suck into the carb.
40:1 is a good start and you can adjust later but I'm thinking probably should be able to put some sort of spacer behind the CVT pulley on the transmission??? Idk but I certainly do enjoy mustie1 videos.
You mean to put the pulley closer together from the beginning? Could work, unless you don't put a spacer between them, stoppg them from getting to full ratio.... 🤔👍
@@horstszibulski19 my main thought was to remove the transmission pulley and install a spacer (if possible) before reinstalling the pulley back on the transmission to align it better with the engine pulley. It would depend on transmission shaft length and thread engagement with whatever fastener is holding the pulley to the transmission. It may or may not be possible.
I built a 3 wheel HARLEY about 15 years ago with a 550 arctic cat engine. Stock rear end would do about 60 mph. Problem is heat burns up those air cooled engines quick. Talk about death wobble!!!
My thought is the crank seals, .... and my reasoning goes like this: with the engine misaligned with the transmission it puts stress on the crank seals allowing them to leak and causing the problem with how the engine revs. ...... solution in my opinion: replace seals, and replace engine mounts, and Aline engine and transmission so belt runs straight again! ...... And I think you will have solved the problem.
Cool cart and as always, a great video! I must gently correct you and point out that CVT = continuously variable transmission (not “constant velocity”).
No that key goes in the front of the doge ram grill you got there ware you were sticking that key I just noticed!!! You make me laugh every time I see your face on your channel!!!🎉🎉🎉🎉🎉
Excellent video Mustie 1 :) also I can say that 440 2 cylinders motor surprises for Yamaha one didn't have 2 carbs with 2 chokes plus throttle too also fuel mixture be 40:1 to 50:1 with 89 5 % Ethonal fuel or 90 or higher octane gas with no Ethonal % ! My late uncle Bill 1974 Bombardier Free / Air 400 Snowmobile had 400 motor orgnailly then when got motor rebuilt in 1990 to 440 size still had 2 carbs plus with 2 choke and throttle cable 2 in one on both also small engine mechanic said use 90 or higher octane gas plus do 50:1 oil and gas in 20 litres geri can each time ! Plus my uncle sled never had problem ever plus he used hot spark plugs platinum too and hot set sparkplugs wires set ! My uncle sled never had oil injection tank or fan cool just air breather type ! But say that motor must be from 1980's possibly and ask what needs is headlights with high and low switche also brake ones too Lol! Nice Snow- Kart with Dodge truck grill and think if lawn tractor back wheels it fly plus emergency brake handle or pedal be great have also canopy roof too !
Question, the CV pulley on the engine, looks like it could close more, but the belt is too short. Would a slightly longer belt climb higher and increase the speed?
JB Weld epoxy the bottom cap/drain. Hmm, lotza bark, no bite. As you were saying, 2 strokes are very sensitive to air bypass (vacuum leaks) .. Nice work.. U Can’t win ‘em all.
I've been watching Mustie1 for years now and every time he checks for spark I think - he needs a couple of croc clips "back to back" to hold the plug firmly on the engine. My OCD kicking in, I guess.
With the online testers you are still fighting the compression. They are better suited when an engine runs but bad to figure out if spark is cutting out intermittently. Personally I also just hold the sparkplug on a metal part somewhere, it just works😂
thats what happens with premixed is the gas evaporates over time and leaves the oil behind so that's probably 25-1 and that's what you seen in the carb way too much oil usually looks like water
I built a very similar machine years ago. Same Yamaha G1 golf cart, originally put a 1 cylinder Kohler engine in, 16hp I think. Then acquired a John Deere snowmobile with a 440 kawasaki air cooled 2 cylinder. I built an entire custom back half to house the engine, new bracket for seats. It had a lift kit and mud tires. I also locked the rear end so both wheels always spun. It was fast and fun in a straight line, but didn't steer very well or stop. I traded it for a honda motorcycle, and then recently saw it for sale again on Marketplace.
Mustie, have you seen Chicanic video showing how crap Trufuel is? It's really interesting to see what differences there are compared to proper 2 stroke fuel.
Canned pre-mix is no good. Do some reading about it online and the issues related to using it. Perform a compression and leak down test pretty much from the get go on an unknown older two stroke engine. Sounds like air leak and or worn rings, scored pistons, rings, and cylinders.
To say it is no good is inaccurate. Look hard enough on the internet and you'll eventually find someone claiming that anything is not good. Those cans contain ethanol free fuel, which is what you want. The only downside is that the oil contained in the premix is not always best quality. If you run your equipment commercially for thousands of hours, you might notice more wear than a top notch synthetic oil. But otherwise, its fine and the shelf life is above average. To blanket state that its no good is not accurate. Ive used and sold hundreds of gallons of that stuff with no issues. What that discussion amounts to is the great and endless oil debate that never gets solved. And no matter whats in that can, it's way better than the crap thats mixed with whatever the government is diluting gasoline with to make it cheaper. You're free to disagree. I just like to elaborate on these trendy topics that suddenly appear on the internet. Cheers my friend!
@giggiddy Not to mention that Mustie seems to go through enough gallons of the stuff that it shouldn't separate, it doesn't stick around on the shelf long enough!
Chickanic has a video demoing the power loss the canned fuels can cause. There's debate over whether this is due to them being crap to begin with or Walmart leaving them sitting on the shelf for 3 years... either way, the price premium on the canned fuel means you can buy the same amount of regular non-ethanol fuel, quality 2 stroke oil, and a container to mix it in and still have change left over after your first can you don't buy.
Thank you for the hours upon hours of entertainment that you have provided. I look forward to your videos. I was just wondering if there would be any more on the bobcat? Thank you and have a great day.
As a kid we had a Yamaha 440 snowmobile that would run just like this rich to lean… bog down all the time, not wanting to idle. Finally gave it away. But my friend had the same machine and his engine was bad ass none of the problems I had.

exactly. Just after primary clutch engagement the belt is already half way up the primary sheave. Belt is way too long.
Way way to long
My first thought on seeing it was there's way too much slack on that belt for the CVT to be working properly.
@@PUGZCAN2 but do those kind of belts get (that much) longer over time? Must be either the wrong belt or it can be tensioned somewhere
Or the two variable pulleys are about 8 inches too close together.

In the 70's people snowmobiling past my bedroom all winter long, 'till the wee hours was the norm. Dozens, if not hundreds of sleds would shoot up the powerlines a few hundred feet away, every night. Now a few rides a year is possible, but 08/09 was the last for a "season" of riding...
I love Mustie’s storage technique, reminds me on the Ludolfs.
About 27 minutes in, music to my soul!
I used to have a Yamaha RD400 or 4.
This one sounds just like it. I'd be
surprised if Yamaha didn't use some
RD400 designs on this engine.

That contraption looks like the aftermath of a collision between a '95 Dodge pickup and a golf cart.
Good Mornin' Mustie! Thanks for taking us along on this interesting project!
Hi Darren, I sent you an email already via the address you have listed, but just in case that address is kaput, I wanted to let you that I have something I'd like to donate to you as a future "will it run" candidate, from down here in Southwest NH. I don't want to give any details here, but will say that it's small and powered by a two-stroke engine. I stumbled across one of your videos about 6 years ago and have been a big fan ever since, thank you for the awesome content!
@Mustie1
Ram-Cart! Awesome man, Thank you for sharing!
Had a Yamaha 440 snowmobile, and man, that thing was FAST! I had my son ride it into my yard. He cracked the throttle and got scared. He bailed, and it ended up wadded up in the neighbors fence. 😳
Son was fine, and the machine survived to live many more snowfalls.
Your patience always amazes me. Id have driven that thing off a cliff about half way through your video, lol. Thanks for another fun video. Long time subscriber here.
He did set fire to it 🔥
A One and a Half Hour Mustie1 feature length show. Grab some popcorn get a drink and settle into your favorite comfy chair.
im in the man cave with 10 cans wish me luck who will finish first
I actually interupted watching the Tampa / Vikings game om my new Samsung CU7000 65" tv to watch this when it popped up on my phones feed.
This was an excellent video to bad it was not successful but very informative and enjoyable thank you for sharing this with us six stars brother
“Watch a guy fill up the tires, whats wrong with you?” Had me laughing so hard 🤣🤣🤣
Defiantly made for great viewing anyway bro. Safe travels. Ken.
A friend of ours built one similar (but my cousin and I didn't know), anyway one summer day Dave and I were outside and I said that I could hear a snowmobile. Finally Dave heard it and it was coming closer, then Steve showed up in a golf cart. I asked Steve about it later , he said it worked great until his friend lost control and hit a tree at the side of his driveway. he used a rotax 340,I think.
My old landlord had a golf cart with a Kubota diesel engine in it.
Pop those two joined engines in this thing and lets see what she'll really do lol another great video can't wait to see what comes next Sunday thx Mustie
Snowmobiles are 'tuned' to run in COLD environments. This means the carburetor is rich to compensate for dense air. Hence, To run in warmer/thinner air, the carb. needs to be leaned out. (both high-speed and low-speed jets) BTW: I am pretty sure that adjustment on the top is IDLE-AIR screw. (clockwise is RICHER at idle)
awesome as always.thanks for sharing and taking us along
I love these videos and it's my Sunday morning ritual to get breakfast and watch Mustie1. I've got to say, the ones were you don't own the project are the least satisfying to watch. They feel unfinished. Even though some of your projects like that Econoline have been going for years with very little progress, there is still hope for their completion. When you pass them back to their owner with a list of problems it's less satisfying.
Mustie1 mouse trap 😂😂 I love your little jokes in your videos. Thanks for the laugh 😅
An air cooled engine designed for use on snow when it's cold out is going to get too hot in warmer weather so it probably isn't ideal for a golf cart. It might have been worn out when it was installed. Even a worn out 440 should have plenty of power to run that cart. Another thing I noticed is that the belt was running on the bottom of clutch on the engine and the top on the drive end which would be the slowest speed. The outer half of the clutch appeared to be moving in but the belt never went further out. Maybe the engine clutch was designed for a wider belt than the golf cart drive uses. Some of the older clutches could be shimmed to close them up. There needs to be a link to keep the distance between the engine and the drive constant to keep the belt tight for the system to function properly.
Very cool. Need to see something old like this run. I agree was hoping for a little more. Thank you for the look into this pretty cool machine.
I love when you go browsing through your junk looking for brackets and stuff. It makes me feel less anxious about the crap I have piled in every corner of my buildings. Thanks for that.
My son drops by looking for stuff and I can see on his face he's thinking about the mess he's gonna have to deal with when I croak. lol
Same here
Same... only mine is old computer parts not car/mower parts.
@@tin2001 Nothing wrong with that.
Scott is going to enjoy watching this!!
Could the hole in the float bowl nut be for draining the float bowl slowly? Like a banjo bolt. Also - a thin sheet of aluminium could be added to curve around the mudguard, and stop the pullstart lead digging in.
He could also have tried all his keys instead of just the one. If you have a bunch of keys, chances are good that one will fit.
Super ⚒🔧🪛...! Great Job 👍
The back hole was throttle cable hook up . The one it was using was for oiler cable to the two stroke tank. But it's working so guess doesn't matter much. Great work brother. Oh and that intake can either put plastic pipe inside to stiffen for a hose clamp. Also could just epoxy together because can just spin whole tube to put filter where u want it.
I have an early 90s Club Car Carryall with an anemic 9hp Kawasaki engine in it. It runs fine but is gutless. Now this has me thinking of a motorcycle, or snowmobile engine swap!
1.1/2 hour mustie1 video ... yipppeeee bring on the coffee & french eclaires 😛
Rolf Cart? LOL, another great video.
Good morning everyone from Alberta, Canada.
Good afternoon from a fellow Albertan! Cheers!
Thanks mustie you have some patience I would have given up ages ago 😊😊😊😊
That's great knew you were having fun with it , I've got an ego with a predator engine in it and it's supposed to do 25to 30 miles an hr
Thanks for the shop time Mustie1!
LOL I have never seen a vehicle rev so hard and go so slow. Good job 👍 PS I don’t think that front CVT pulley is working correctly, it’s not closing up far enough to give you a higher gear ratio. Yep crank seals for sure I would say.
I thought that as well. The rearcvt doesn't appear to be working properly either.
I'm suspecting the clutch also, maybe Mustie smoked it with the burn out test against the forklift, would add up to the problems with the seals and fuel mixture...
👍
Actually, it's probably the secondary clutch causing the problem. If I remember correctly, Darren said that the secondary clutch is the one which came with the golf cart. If you look at the drive belt, it seems to be a perfect fit for the secondary clutch and when he fully revs the motor there is still a gap between the belt and the primary clutch. The issue is the primary clutch can't close enough to grip the belt properly and I doubt you could adjust it enough for this belt. My guess is the snowmobile the engine came out of has a wider secondary clutch (and thus, a wider belt) than the golf cart's and there's probably a good chance the snowmobile's secondary clutch wouldn't fit on the golf cart.
Good job investigating! I can't believe no one blows off or cleans these carts before working on them. You had a pine needle trying to suck into the carb.
40:1 is a good start and you can adjust later but I'm thinking probably should be able to put some sort of spacer behind the CVT pulley on the transmission??? Idk but I certainly do enjoy mustie1 videos.
You mean to put the pulley closer together from the beginning? Could work, unless you don't put a spacer between them, stoppg them from getting to full ratio....
🤔👍
@@horstszibulski19 my main thought was to remove the transmission pulley and install a spacer (if possible) before reinstalling the pulley back on the transmission to align it better with the engine pulley. It would depend on transmission shaft length and thread engagement with whatever fastener is holding the pulley to the transmission. It may or may not be possible.
I built a 3 wheel HARLEY about 15 years ago with a 550 arctic cat engine. Stock rear end would do about 60 mph. Problem is heat burns up those air cooled engines quick. Talk about death wobble!!!
My thought is the crank seals, .... and my reasoning goes like this: with the engine misaligned with the transmission it puts stress on the crank seals allowing them to leak and causing the problem with how the engine revs. ...... solution in my opinion: replace seals, and replace engine mounts, and Aline engine and transmission so belt runs straight again! ...... And I think you will have solved the problem.
"Found this this Ratty old Rolf Cart with a Big Engine" will let it slide as it's a Sunday :D Love the video Darren
Cool cart and as always, a great video! I must gently correct you and point out that CVT = continuously variable transmission (not “constant velocity”).
No that key goes in the front of the doge ram grill you got there ware you were sticking that key I just noticed!!! You make me laugh every time I see your face on your channel!!!🎉🎉🎉🎉🎉
Was waiting for a broom stick throttle when Mustie was trying to crank and hit the gas at the same time😅
Excellent video Mustie 1 :) also I can say that 440 2 cylinders motor surprises for Yamaha one didn't have 2 carbs with 2 chokes plus throttle too also fuel mixture be 40:1 to 50:1 with 89 5 % Ethonal fuel or 90 or higher octane gas with no Ethonal % ! My late uncle Bill 1974 Bombardier Free / Air 400 Snowmobile had 400 motor orgnailly then when got motor rebuilt in 1990 to 440 size still had 2 carbs plus with 2 choke and throttle cable 2 in one on both also small engine mechanic said use 90 or higher octane gas plus do 50:1 oil and gas in 20 litres geri can each time ! Plus my uncle sled never had problem ever plus he used hot spark plugs platinum too and hot set sparkplugs wires set ! My uncle sled never had oil injection tank or fan cool just air breather type ! But say that motor must be from 1980's possibly and ask what needs is headlights with high and low switche also brake ones too Lol! Nice Snow- Kart with Dodge truck grill and think if lawn tractor back wheels it fly plus emergency brake handle or pedal be great have also canopy roof too !
Question, the CV pulley on the engine, looks like it could close more, but the belt is too short. Would a slightly longer belt climb higher and increase the speed?
JB Weld epoxy the bottom cap/drain.
Hmm, lotza bark, no bite.
As you were saying, 2 strokes are very sensitive to air bypass (vacuum leaks) .. Nice work.. U Can’t win ‘em all.
I used to work on those ( as snowmobiles) i do beleive it has 440 cc displacment ( you are right about 40 HP)
50 horses according to google. That thing absolutely rips lol!
Hi Mustie. Great video!! The motor is tired like me, lol. Hope you have a great week!!👍
Brian from Ma.Great video always learn a bunch Thanks Besafe
Warning: this episode is NOT E.P.A. Compliant 😂
Hate the epa
Mustie- you have more “junk” in your garage than I do- I’m impressed!!! Keep on wrenchin’ !!
Good Morning, Mustonians!
Mustie, since watching you I have learnt alot , not to be too gentle.. 😂 yep belt it a bit.😮
I've been watching Mustie1 for years now and every time he checks for spark I think - he needs a couple of croc clips "back to back" to hold the plug firmly on the engine. My OCD kicking in, I guess.
He had an inline spark tester, for about two shows.
With the online testers you are still fighting the compression.
They are better suited when an engine runs but bad to figure out if spark is cutting out intermittently.
Personally I also just hold the sparkplug on a metal part somewhere, it just works😂
@@samuraidriver4x4 until it slips off and you become the path to ground. 😂😂
@@markbrown8097 that is a bit of a shocking experience but not to bad😂
I was thinking the same, think he likes the struggle thou, and that hammer!
Finding that in a free pile would be a dream come true!!
thats what happens with premixed is the gas evaporates over time and leaves the oil behind so that's probably 25-1 and that's what you seen in the carb way too much oil usually looks like water
It looks like it has an external oil inject system.
@@robertchapin3683 might have but that's premixed fuel there's hardly a sole that would trust one of those oil injectors
I'm one of those souls. I had the system removed from my 75 hp Mercury last year.@@grapphiiczak
I built a very similar machine years ago. Same Yamaha G1 golf cart, originally put a 1 cylinder Kohler engine in, 16hp I think. Then acquired a John Deere snowmobile with a 440 kawasaki air cooled 2 cylinder. I built an entire custom back half to house the engine, new bracket for seats. It had a lift kit and mud tires. I also locked the rear end so both wheels always spun. It was fast and fun in a straight line, but didn't steer very well or stop. I traded it for a honda motorcycle, and then recently saw it for sale again on Marketplace.
Mustie, have you seen Chicanic video showing how crap Trufuel is? It's really interesting to see what differences there are compared to proper 2 stroke fuel.
Cool video Mustie 👍👍
Could you put a link in for that battery powered fuel pump. Thanks
Harbor Freight has a cheap one that works pretty good I've had it for a few years
Link 👀
Always look forward to Sunday here in the UK for your videos
Can you tell me where you got the fuel suction tool you used to get the gas out of the tank ? Very cool little tool and would love to have one.
I've seen them a Rural King and Tractor Supply
I have a manual one but I would definitely like a powered one.

I do like the longer video format!
Canned pre-mix is no good. Do some reading about it online and the issues related to using it.
Perform a compression and leak down test pretty much from the get go on an unknown older two stroke engine. Sounds like air leak and or worn rings, scored pistons, rings, and cylinders.
To say it is no good is inaccurate. Look hard enough on the internet and you'll eventually find someone claiming that anything is not good. Those cans contain ethanol free fuel, which is what you want. The only downside is that the oil contained in the premix is not always best quality. If you run your equipment commercially for thousands of hours, you might notice more wear than a top notch synthetic oil. But otherwise, its fine and the shelf life is above average. To blanket state that its no good is not accurate. Ive used and sold hundreds of gallons of that stuff with no issues. What that discussion amounts to is the great and endless oil debate that never gets solved. And no matter whats in that can, it's way better than the crap thats mixed with whatever the government is diluting gasoline with to make it cheaper. You're free to disagree. I just like to elaborate on these trendy topics that suddenly appear on the internet. Cheers my friend!
@giggiddy Not to mention that Mustie seems to go through enough gallons of the stuff that it shouldn't separate, it doesn't stick around on the shelf long enough!
@@davidreese9984 very true!!! Lol. Cheers!
Chickanic agrees the premixed fuel is not great.
Chickanic has a video demoing the power loss the canned fuels can cause. There's debate over whether this is due to them being crap to begin with or Walmart leaving them sitting on the shelf for 3 years... either way, the price premium on the canned fuel means you can buy the same amount of regular non-ethanol fuel, quality 2 stroke oil, and a container to mix it in and still have change left over after your first can you don't buy.
Thank you for the hours upon hours of entertainment that you have provided. I look forward to your videos. I was just wondering if there would be any more on the bobcat? Thank you and have a great day.
Very cool to see that 1994-2002 Dodge Ram grille on the golf car
As a kid we had a Yamaha 440 snowmobile that would run just like this rich to lean… bog down all the time, not wanting to idle. Finally gave it away. But my friend had the same machine and his engine was bad ass none of the problems I had.
