You need to change the spark plugs. those engines benefit greatly from fresh plugs, as they foul plugs easily. Your jetting is more than likely off because it's jetted for winter temperature. And also snowmobile engines are very sensitive to clutching. You guys are leaving a good 30%-40% of HP on the table. Thank you guys great work

I think that's what the Issac's slow lap was about. He was rolling the thing around the track part throttle on cold tires. The second lap he started leaning on it and warming the tires up and then he went for it.
@@shawnstillman736 that's part of it.. but the pressure waves in the pipe push it back onto the combustion chamber, basically superchariging it. The more air:fual you can jam into the engine, the more power it'll make. this is why they are so sensitive to the exhaust system.. hence the term "tuned pipe" and when it is operating at its highest efficiency, that is "on the pipe", you can change the way the power is made by changing the pipe. That's also why 9/10 snowmobile powered go karts have less than half the engine's stock HP. Nobody seems to understand this lol
If you can adjust your front wheel camber to a little positive, when you sit in the kart you'll have neutral camber and a full contact patch on the tire. This will help get rid of the understeer.
At least the frame is made with removable spindle brackets... Shouldn't be too bad to make one of those. or ya could make a set of two that accept newer style spindles w/ eccentric bearings for adjustment. I wouldn't doubt that back around when that frame was made, the manufacturer had sets of those brackets available with different camber angles built into them. I suppose the main thing is: do ya really feel like doing the work?! hehe :D
@@CarsandCameras There is no such thing as "fixed camber" or "fixed caster"... When I was 14 I worked at 'Tustin Lawnmower and Bicycle Shop' in California. Learned a lot. We had a digging bar (a six foot solid 1 inch spring steel bar) with a steel steering bushing welded to the end at about a 45 degree angle. There was a section of concrete out back with what appeared to be random loops of steel coming out of the concrete. This was a genius idea, and served as our "frame rack" for fixing anything that was bent. On about 50% of the go-karts that came into the shop we would do a "safety alignment" $20 extra (1981 dollars...that's like 2.5 gallons of gas in 2022 dollars) I put a 6X6 under the front and back of the cart and tied it down with criss cross ratchet straps tight tight tight. It was then easy to determine if the king pin bolt, or warn steering axles were the issue or if I needed to put the kingpin bolt through the tool and give her a quick adjustment. You can easily bend the frame to dial in the caster and KPI (king pin inclination). Obviously we sold a lot king pin bolts, and would even reweld and line bore (reem) the holes for a nice tight fitting steering knuckle. We also would weld gussets on if reinforcement was required. I loved that job and prided myself in the fact that I doubled the cost of the average go-kart repair ticket while simultaneously increasing customer satisfaction. (We had an area 'out back' where customers could safely ride them before paying the bill that was way more than they expected). This job is why I decided to get a degree in automotive technology.

It sounded like two people talking impossibly fast to each other in some otherworldly language over a pretty good distance on either side of a bay we were in. We sat out in the boat for a good 15 minutes hearing the same sound occasionally until it seemed to stop. We decided to go in and as were were dragging the boat onshore the sounds started again, only really close. Then we heard a big crash in the brush and what was basically half a dead tree landed about ten feet away from us. Our car was 200 feet up a dirt landing and we ditched our fishing stuff and ran to it. Once we were in the car we felt pretty safe, but we still had to get the boat and our gear. We had some fireworks in the car so we decided to use them to try to scare whatever it was we thought we were hearing away.

I was on a reality TV show once (about bad drivers) and they put me in an 125cc Shifter Kart (top level racing cart / liquid cooled) to run laps against a Canadian champion. People will never know how hard it is on the body to keep these way-over-powered machines on the track. I spun on the 2nd lap and couldn't endure any more. They said I did 100mph!.. but I think more like 80. I'll bet you had a blast. Way ta' go lads!
@@ontariotube were the drivers really that bad I've seen the last season on the seven seas but wow I thought people in stl drove like shit. Some dipshit yesterday tried getting in a lane war with my service truck which was a 389 with a service body and I was pulling a mini ex. He was driving a v6 charger
I remember when there were many Go kart tracks everywhere. You can still see their remains along many roads. Glad to see some of them are still out there
I can tell just from hearing that it’s way to rich. It’s loading up and that’s why you are running into plugs fouling. Also leaning it down will help it’s acceleration. You gotta remember that it set up to run 20 degree and colder weather.
I came here to say the same thing. I wonder if they kept the jetting the same as it was from how it was equipped in a snowmobile? Assuming stock jetting from the factory is typically good from 0-20 degrees F. You could easily go down 2 jet sizes and maybe even drop the needles a notch to clean up the mid range. It's possible you could even go leaner because the time spent in the mid range and WOT is so short on an application like this.
@@ttank1994 I know when I was racing sleds I could go down four sizes on my main jet from the hottest race in the spring to the coldest race in the winter. Eventually I just stayed with 3 just, because the sled was more consistent and I didn’t run into heating issues.
@@sparky87213 I definitely believe it. I stayed conservative recommending 2 sizes because I don't know what's in it now and if these chuckle heads didn't know enough to address the jetting right away then they would probably take it way lean just as easy.
This is cool guys!!! I raced 500cc two stroke (non roll cage) karts on dirt tracks in central Fl in the 90’s, and raced 125cc shifters professionally in the early 2000’s. Get that thing corner balanced (best as you can), geared correctly, and put some front brakes on it and it will be a lot more fun, safe, and quick.
Driving 2 strokes off the gas that long and cruising will definately foul your plugs. Contstat bliping is needed and of course the balls of steel to drive that concotion on the track. The power is insane but handling is hurt.
In my experience those “pocket speedos” aren’t very good at quick blasts of acceleration, you need to hold the speed for a little while to get a good reading. So it may be impossible to get an accurate number on a track like that.
Awesome, the stooge really Sent it, that would be a fun ride, Reminds me of my old Artic Cat legit tuned racing snowmobile in the 70's, it ran multiple 1/4 mile passes on the ice, on the trails was a beast as long as the slower speeds didnt foul the plugs
What an awesome track. Of course he's gonna let you run, you're an established channel now. Even if one of you died on his track you signed a waiver, and any publicity is good publicity. ;)
Learned about the track years ago when the company I worked for took us out for a day (freaking awesome bosses lol). I went back a few years later as a birthday celebration for myself, along with friends and family. Both of those times we ran the track reverse from how these guys did. Not sure why it was changed, but all in all, it was an absolute blast!! Our previous experience had been nothing more than the watered down go-karts you find at vacation destinations. We were blown away by the speed of the karts and layout of the track. Love that place! :)
Should be plenty where you are. I 1200cc 4 stroke swapped a 4 wheeler. It was ridiculous. Did 300' race on dirt in the high 3 second average. And did 100 mph easily. Your turbo raptor mower should get close to that with some good scoops 👍
As others have mentioned you need to rejet the engine for the warm temperature as it is running way too rich. Clutching is likely off as well. Engine is bogging bad.
That is an AWESOME race track. I'd love to take my go kart there but I live clean across the Country in Washington State. that 670 go kart is definitely fast but I think it could use a lot more tire on it. a little taller and wider all the way around. along with the the upgrades that you talked about. it definitely looks like it would be a blast to rip around that track in that kart. I'm betting that I could shave off some more time off that fast lap. time once I got to know the layout of that track. no matter it would still be a blast trying to anyway. something that you need to do is put that kart on some scales. just to see what the right and left side weight is. I bet it's like 80/20 or 90/10 percent without the driver. that's always going to make it handle poorly turning one way than to the other. the only cure for that would be to widen the the wheel track out so the engine is inside the wheels. and have a driver that is equal weight. that is a lot of weight hanging outside those wheels. but all and all it looked like a blast no doubt.
I have to tell you guys. I laughed so frigging hard when your professional driver "The Stooge" came out of the porta-potty, wiping off his face shield trailing a length of TP behind him on the way to the cart, I thought I was going to piss myself. Frigging hilarious.
Awesome kart! I'd love to see what this thing would do on a drag strip. I can't wait to see this at its best! Thanks guys! LOL! The Stoog right out of the port-a-potty.
Great build! Im guessing u beefed up the chassis for that engine which eliminated ur chassis flex which might be why u cant turn right. Also, definitely add some front brakes! 🤘🏻
It looks to me like the right front has more camber than the left front .This could be why you are having trouble turning right. I am not an expert by any stretch of the imagination just an observation.
Well done lads watch all your vids seeing you all ripping around that track made me smile so much cant wait to see more content on this build well done
Only way to fix the right hand cornering issue is to fix the weight balance problem.... Or maybe mix up the tire sizes and pressures..... Something... That would drive me nuts.... And better brakes. The Stooge almost lost it going into that first corner...
Two words: Power Washer. (Bringing dirt onto a pavement track is unsportsmanlike) Two more: Front Brakes. (Slowing down contributes a lot to lap times) Two more: Chassis Flex (To fix the handling) Basically, the way that a kart with a straight axle can steer/turn is to break traction on the inside rear tire, by lifting vertical pressure on it just enough that the outer tire dominates. Your kart can't get the RR to lift, so you can't turn right effectively. In a better balanced kart (scale this beast with a driver in the seat, not empty) it is accomplished with the "waist" or narrower part of the chassis behind the front wheels. So, here are some band-aids which might help. 1. Offset the rear axle to the right as much as you can. 2. Move the radiator to the left as much as you can. 3. Offset the driver's seat to the left if you can. 4. Raise the ride height of the left side of the rear axle. 5. Add caster/camber pills to the LF corner, and increase the caster on that wheel. Maybe raise that ride height just a little too. 6. When driving, lean your body against the seat to the *Outside* of the corner. (seems unnatural, but remember what it is you want to do, and why) I haven't gotten a look at the chassis or steering system. The chassis must be allowed to twist a bit. Too stiff, and you go straight. The inner tie rod ends must be separated by a bit in the cross-chassis direction. If they are stacked on top of each other, there will not be sufficient Ackerman, and too much scrub. Keep up the entertaining vids! Edit: Note that none of these adjustments need be big ones. Every little bit can help a lot, and with some, 1/4 inch is huge! All together, they may go a ways towards giving you a better balance on the track. One more thing... The plug fouling issue may be caused by a dirty air filter. You ran the kart in off-road left turns a lot, and powder clogging the pleats can really change the air-fuel ratio.
Definitely check your jetting as well. Those snowmobile engines are jetted to run at 0 degrees and less with more dense air therefore will run super fat and foul plugs at 70 degrees.
Throw E3 plugs in that thing! I ran an E3 in my kdx200 and it never fouled ever and i had it in low crawl boggy chug all the way to screaming peak powerband and it just ate it up like it was nothing. It did pick up a bit more spunk off the line with the E3 as well.
Got to get that motor sorted out. Also make some upgrades and stuff to the chassis and work all the bugs out. I think it would be really cool too if you tear down and rebuild and paint the thing!
I stand by what I said in one of the previous videos: Widen the track and frame and fully support that engine from the front wheel to the rear. I'd also say widen the rear axle to the max you can order off the shelf (if it isn't there, already) and try to offset the track a little to the engine side in order to assist balance. That plus some larger and wider tires, plus FRONT BRAKES, and you'll be RIPPIN triple digit speeds somewhere with moderate safety, lol.
Actually, I also found THESE guys with 670 2 stroke karts. Medium wheelbase, engine mostly behind driver, long front overhang. Things RIP. th-cam.com/video/hVmM3AtCdh8/w-d-xo.html
Well guys, I'm quite surprised that John doesn't realize this, but that engine is running very lean. That's why it bogs, and why it runs and sounds the way it does. Lean runs KILL two strokes fast, and the only reason you haven't blown it up is because it is so over powered and thus lightly loaded. It's probably lean because it no longer has the restrictive factory air box. When tuning these type carbs, know this great tip. The choke circuit provides additional fuel at ANY speed/throttle setting. Turn on the choke, and if it runs better, STOP immediately and richen up whatever circuit you were running on. (Idle, mid range, wide open/main circuit., etc.) Lastly, note that at wide open throttle, the neddle has been pulled all the way out of the needle jet and is no longer a factor. A common tuning trick is to take out the main jet completely and run it. This will tell you if the NEEDLE JET itself will flow enough fuel at WOT for that engine. If not, install a larger NEEDLE JET, and go from there with your usual jetting process with the idle jet, main jet, needle height setting, etc. Your AFR gauge will work on that two stroke too. Just don't run the O2 sensor for extended driving as it will get dirty. The four stroke on the dragster sounds fantastic, but just think what this two stroke would do. Hint, hint... Good luck!
Cheers from Canada! Dudes, our engines run rich for an obvious reason. If you're not ripping from 75% to 100% (which because the track in the snow adds a ton of drag) all the time you're foul the plugs constantly. Keep er hot and pinned!
Ike - John - Charles. You Have Alot Of Amazing Builds And This Is One Of My Favorites. Thank's For Taking Me Along For The Ride. Keep The Videos Comeing. Thank's Again
It might sound odd to you guys since you don't have much 2-smoke experience, especially snowmobile engines. But one thing you want to keep an eye on with an engine like the 670 is making sure you use the correct 2 stroke oil for your pre-mix. You might be already, who knows. But the Rotax engines use RAVE power valves in them instead of standard reed valves. That's what those black "pods" are above the exhaust ports on your exhaust side. You'll want to make sure the pre-mix oil you're using is designed for engines with power valves in them or else it'll gum up the power valves. Which will also cause performance issues for you. :)
To fix the turning right issue you HAVE TO .... for safety and drive-ability..... ADD another 670 to the left side to even it up !! Might get into the 20's =))
For the safety and drive ability🤣🤣
@@thehourglasswithaman Well, if you have a rocket, and its tilting to one side since the engine is offset and forced to vector the nozzle, if you can't move the rocket motor, just add another nozzle to balance it out. As KSP taught me, moar boosters!
Dont think it'd be torque steering, as is a solid axle, right? But the weight balance is probably the factor. Counter weighting it might help.
MIIIIIIINT MAKE IT 4WD

I came here to say the same thing. I wonder if they kept the jetting the same as it was from how it was equipped in a snowmobile? Assuming stock jetting from the factory is typically good from 0-20 degrees F. You could easily go down 2 jet sizes and maybe even drop the needles a notch to clean up the mid range. It's possible you could even go leaner because the time spent in the mid range and WOT is so short on an application like this.
@@ttank1994 I know when I was racing sleds I could go down four sizes on my main jet from the hottest race in the spring to the coldest race in the winter. Eventually I just stayed with 3 just, because the sled was more consistent and I didn’t run into heating issues.
@@sparky87213 I definitely believe it. I stayed conservative recommending 2 sizes because I don't know what's in it now and if these chuckle heads didn't know enough to address the jetting right away then they would probably take it way lean just as easy.
@@ttank1994 "chuckle heads" I dunno why, but that word is just pure gold! lol
Is it me or does it sound lean at idle?
This is the first comment I ever sent.. when Charles did a 360 I sead to my self...I love you guys....
Just fantastic!! Great idea, great build and great fun. Well done lads
This is cool guys!!! I raced 500cc two stroke (non roll cage) karts on dirt tracks in central Fl in the 90’s, and raced 125cc shifters professionally in the early 2000’s. Get that thing corner balanced (best as you can), geared correctly, and put some front brakes on it and it will be a lot more fun, safe, and quick.
Love this episode would love to see other builds out at that track
Driving 2 strokes off the gas that long and cruising will definately foul your plugs. Contstat bliping is needed and of course the balls of steel to drive that concotion on the track. The power is insane but handling is hurt.
gotta stay on the pipe.
In my experience those “pocket speedos” aren’t very good at quick blasts of acceleration, you need to hold the speed for a little while to get a good reading. So it may be impossible to get an accurate number on a track like that.
great stuff thanks that thing looked really fast
always good to see the boys having fun!
Awesome, the stooge really Sent it, that would be a fun ride, Reminds me of my old Artic Cat legit tuned racing snowmobile in the 70's, it ran multiple 1/4 mile passes on the ice, on the trails was a beast as long as the slower speeds didnt foul the plugs
Get it sorted please, we definitely want to see more of this insane kart!
I have a deep love for this cart, engine dang near hanging out the right side and fast as HELL!!!!!
What an awesome track. Of course he's gonna let you run, you're an established channel now. Even if one of you died on his track you signed a waiver, and any publicity is good publicity. ;)
Learned about the track years ago when the company I worked for took us out for a day (freaking awesome bosses lol). I went back a few years later as a birthday celebration for myself, along with friends and family. Both of those times we ran the track reverse from how these guys did. Not sure why it was changed, but all in all, it was an absolute blast!! Our previous experience had been nothing more than the watered down go-karts you find at vacation destinations. We were blown away by the speed of the karts and layout of the track. Love that place! :)
Dudes... REAL Drift cart... OMG so epic!!!
now in search for a two stroke snowmobile motor.
Should be plenty where you are. I 1200cc 4 stroke swapped a 4 wheeler. It was ridiculous. Did 300' race on dirt in the high 3 second average. And did 100 mph easily. Your turbo raptor mower should get close to that with some good scoops 👍
488 polaris twin is the best go kart engine. Fan cooled, low end grunt, plenty of power, fairly light, stupidly easy to fix, dead nuts reliable.
Yes! And put trash kitty in charge!
I have a lot and you can't have even one because they're staying in the sleds.
Just get any old motor bike engine and gearbox and it will be quicker then this.
Incredible video and VIR ROCKS..
BLESS THEM. How fun... you 3 mad scientists are the greatest. Hey Charles!!!!
As others have mentioned you need to rejet the engine for the warm temperature as it is running way too rich. Clutching is likely off as well. Engine is bogging bad.
Right we need timed laps with all your vehicles on this track now! Cheers for another sweet vid legends
Now I feel like y'all gotta get every project out here to run a time lmao.
“It’s very controllable” meanwhile it can’t turn right 😂. Great video boys!
That is an AWESOME race track. I'd love to take my go kart there but I live clean across the Country in Washington State. that 670 go kart is definitely fast but I think it could use a lot more tire on it. a little taller and wider all the way around. along with the the upgrades that you talked about. it definitely looks like it would be a blast to rip around that track in that kart. I'm betting that I could shave off some more time off that fast lap. time once I got to know the layout of that track. no matter it would still be a blast trying to anyway. something that you need to do is put that kart on some scales. just to see what the right and left side weight is. I bet it's like 80/20 or 90/10 percent without the driver. that's always going to make it handle poorly turning one way than to the other. the only cure for that would be to widen the the wheel track out so the engine is inside the wheels. and have a driver that is equal weight. that is a lot of weight hanging outside those wheels. but all and all it looked like a blast no doubt.
I have to tell you guys. I laughed so frigging hard when your professional driver "The Stooge" came out of the porta-potty, wiping off his face shield trailing a length of TP behind him on the way to the cart, I thought I was going to piss myself. Frigging hilarious.
I wish you had also brought the Ducarti so you could've raced them!
By far one of my favorite videos! Love this guys! That kart looks like a blast……. Literally!!!
I see an asphalt track on the property in the near future. Make it happen boys.
We gonna need to raise some money!
Those top gear references are legendary
Gotta oil those air filters. It will keep dust out of the engine
Could see dust fall out when he tested for flex.Why the hell they didn't clean them after the yard is always a pisser.
Awesome kart! I'd love to see what this thing would do on a drag strip. I can't wait to see this at its best! Thanks guys! LOL! The Stoog right out of the port-a-potty.
No one would be able to pass you on the track, because that cart is 6 feet wide! 😆
I love Charles more every episode 🤣 he keeps me rolling! he reminds me so much of a best friend from about 15-20 years ago!
Great build! Im guessing u beefed up the chassis for that engine which eliminated ur chassis flex which might be why u cant turn right. Also, definitely add some front brakes! 🤘🏻
Now were talking boys. But the beast to a real test. Proud of you for wearing safety gear to the recommended level. Thumbs up
It looks to me like the right front has more camber than the left front .This could be why you are having trouble turning right. I am not an expert by any stretch of the imagination just an observation.
I also noticed that. the left front definitely has more negative camber than the front left
Holy smokes! That thing sure cooks! Nice build, guys! Well done.
I’m digging the Keith urban hairstyle on IKE
Great work having them supporting you guys!
NOW, that was a FULL SEND. Good job.
Love you guys video. You actually take the time and explain it so most everyone can understand. Keep having fun and thank you..
Great video guy's!!!..... lotsa fun was had by all !!!!..... impressive build and editing !!
Thanks for thr thrill rides gentlemen! Put an eighty five horse bolt on jet engine on the left side and fly into those right turns.
Great driving!
Well done lads watch all your vids seeing you all ripping around that track made me smile so much cant wait to see more content on this build well done
Wow! What a ride! Great build guys!
That brought back some memories for me. Old Mac twin cart my buddy had. They made me the pilot cus I was smallest (youngest). Thank y'all very much!
Only way to fix the right hand cornering issue is to fix the weight balance problem.... Or maybe mix up the tire sizes and pressures..... Something... That would drive me nuts....
And better brakes. The Stooge almost lost it going into that first corner...
That thing is cool I would love to drive it myself great job guys
Now you guys have to take it to the drag strip and compare it to some of your other ridiculous kart builds. Nice job!
The spark plug dancing around @ 4:40 was a nice touch.
Two words: Power Washer. (Bringing dirt onto a pavement track is unsportsmanlike)
Two more: Front Brakes. (Slowing down contributes a lot to lap times)
Two more: Chassis Flex (To fix the handling)
Basically, the way that a kart with a straight axle can steer/turn is to break traction on the inside rear tire, by lifting vertical pressure on it just enough that the outer tire dominates. Your kart can't get the RR to lift, so you can't turn right effectively. In a better balanced kart (scale this beast with a driver in the seat, not empty) it is accomplished with the "waist" or narrower part of the chassis behind the front wheels. So, here are some band-aids which might help.
1. Offset the rear axle to the right as much as you can.
2. Move the radiator to the left as much as you can.
3. Offset the driver's seat to the left if you can.
4. Raise the ride height of the left side of the rear axle.
5. Add caster/camber pills to the LF corner, and increase the caster on that wheel. Maybe raise that ride height just a little too.
6. When driving, lean your body against the seat to the *Outside* of the corner. (seems unnatural, but remember what it is you want to do, and why)
I haven't gotten a look at the chassis or steering system. The chassis must be allowed to twist a bit. Too stiff, and you go straight. The inner tie rod ends must be separated by a bit in the cross-chassis direction. If they are stacked on top of each other, there will not be sufficient Ackerman, and too much scrub.
Keep up the entertaining vids!
Edit: Note that none of these adjustments need be big ones. Every little bit can help a lot, and with some, 1/4 inch is huge! All together, they may go a ways towards giving you a better balance on the track. One more thing... The plug fouling issue may be caused by a dirty air filter. You ran the kart in off-road left turns a lot, and powder clogging the pleats can really change the air-fuel ratio.
I'm not sure who had a bigger smile on their face me or you guys 😁
Get it to the drag strip
My absolute favorite channel on TH-cam
CHARLES DONE A 29MPH DONUT!! 🤪👍
👊✊️💥💨💨💨💨
This is the single greatest thing you guys have ever done and it's only going to get crazier
You read my mind! I was thinking about how fun that would be to take it around the local go-cart track!
Your pro racing driver is seriously brave. No screaming or anything while driving that thing.
Charles has some good throttle control.
Thats one thing I love about y'alls channel you build and use em
Definitely check your jetting as well. Those snowmobile engines are jetted to run at 0 degrees and less with more dense air therefore will run super fat and foul plugs at 70 degrees.
Throw E3 plugs in that thing! I ran an E3 in my kdx200 and it never fouled ever and i had it in low crawl boggy chug all the way to screaming peak powerband and it just ate it up like it was nothing. It did pick up a bit more spunk off the line with the E3 as well.
Got to get that motor sorted out. Also make some upgrades and stuff to the chassis and work all the bugs out. I think it would be really cool too if you tear down and rebuild and paint the thing!
I dig your artificial laugh John
That was awesome!
I stand by what I said in one of the previous videos: Widen the track and frame and fully support that engine from the front wheel to the rear. I'd also say widen the rear axle to the max you can order off the shelf (if it isn't there, already) and try to offset the track a little to the engine side in order to assist balance.
That plus some larger and wider tires, plus FRONT BRAKES, and you'll be RIPPIN triple digit speeds somewhere with moderate safety, lol.
Actually, I also found THESE guys with 670 2 stroke karts. Medium wheelbase, engine mostly behind driver, long front overhang. Things RIP. th-cam.com/video/hVmM3AtCdh8/w-d-xo.html
Well guys, I'm quite surprised that John doesn't realize this, but that engine is running very lean. That's why it bogs, and why it runs and sounds the way it does. Lean runs KILL two strokes fast, and the only reason you haven't blown it up is because it is so over powered and thus lightly loaded. It's probably lean because it no longer has the restrictive factory air box.
When tuning these type carbs, know this great tip. The choke circuit provides additional fuel at ANY speed/throttle setting. Turn on the choke, and if it runs better, STOP immediately and richen up whatever circuit you were running on. (Idle, mid range, wide open/main circuit., etc.)
Lastly, note that at wide open throttle, the neddle has been pulled all the way out of the needle jet and is no longer a factor. A common tuning trick is to take out the main jet completely and run it. This will tell you if the NEEDLE JET itself will flow enough fuel at WOT for that engine. If not, install a larger NEEDLE JET, and go from there with your usual jetting process with the idle jet, main jet, needle height setting, etc.
Your AFR gauge will work on that two stroke too. Just don't run the O2 sensor for extended driving as it will get dirty.
The four stroke on the dragster sounds fantastic, but just think what this two stroke would do. Hint, hint...
Good luck!
"...and then it's like, freight train mode. Like, straight rocket ship!"
The two most conflicting back to back statements in the history of words.
Let's go!!!! Get sent home early to a fresh upload, couldnt ask for a better way to cheer me up!
Absolutely love the Top Gear reference! Amazing
I predict this video will catch the best views of any of your previous videos.
Y'all have created a monster.
Fuel feed needs sorting,muffler adjusted bigger air box and your good to go, impressive
Cheers from Canada! Dudes, our engines run rich for an obvious reason. If you're not ripping from 75% to 100% (which because the track in the snow adds a ton of drag) all the time you're foul the plugs constantly. Keep er hot and pinned!
You guys should bring your projects here more often.
They guy y’all had racing that go kart in the video was hilarious
Take this and the ducarti to a local drag strip and settle the beef!!! Everyone like this so we can see the best drag race of this channel!!!
All I can say is "yes indeed" guys you nailed it
And now you know why snowmobiling is the greatest hobby ever.
Ike - John - Charles. You Have Alot Of Amazing Builds And This Is One Of My Favorites. Thank's For Taking Me Along For The Ride. Keep The Videos Comeing. Thank's Again
I have a 97 Ski-Doo MXZ 670, at just over 500lbs dry it was crazy fast when you got good traction. That cart must be blistering. Awesome!
It might sound odd to you guys since you don't have much 2-smoke experience, especially snowmobile engines. But one thing you want to keep an eye on with an engine like the 670 is making sure you use the correct 2 stroke oil for your pre-mix. You might be already, who knows. But the Rotax engines use RAVE power valves in them instead of standard reed valves. That's what those black "pods" are above the exhaust ports on your exhaust side. You'll want to make sure the pre-mix oil you're using is designed for engines with power valves in them or else it'll gum up the power valves. Which will also cause performance issues for you. :)
The stooge and the toilet paper was hilarious 🤣
Now this is wut I was waiting for
I would have said "yes! Let's do it!" Which would be something because it takes a lot to get me excited.
