If I heard that sound, before I saw the car, and then saw the car I would be extremely confused. Im sure that's an added bonus of what you do. Keep on pluggin' away Jimbo!
An old hot rod trick for infinitely adjusting the same carburetor jet is by drilling out the hole to the desired size but if you go too big you can just solder it closed and redrill it as many times as you need. 👍
That's what I did tuning my bicycle. Kept drilling it out one size at a time then solder and drill the last size down when the spark plug appeared rich.
The algorithm presented me with your channel a few months ago, and I can’t get enough of it. It’s scary to know how well the algorithm understands my interests.
I'm going to suggest it again cut the center out of the carburetor spacer and it will make the carburetor bigger I'll guarantee a horsepower increase and speed

Any plans for a Tachometer? I'm really curious to know what RPM the CVT holds the engine at during hard acceleration and is that adjustable? I.e. Putting out peak HP rpm for all the acceleration, or does that only occur at the end of an acceleration run? In other words, how tunable is the CVT? Acceleration run at 3000rpm vs 3600rpm would yield some different results I suspect.
A cheap but very effective EMI attenuator for small engines is a common stainless steel braided plumbing hose like what is used under sinks. Just use a size that the stock spark plug wires will fit through and cut it to length and ground the braided SS jacket to the block. It won't take all of the noise out but it will knock it down considerably.
Sounds expensive. I was thinking kitchen foil on the plug wires. Also make sure there's a resistor in the ignition line, either resistive wire or a resistive spark plug.
@@robotcantina8957can you register Side By Side UTVs?

I would have at least liked to hear the first muffler with the baffle in place. You're already adapting up just to fit the muffler, so I doubt the restriction is actually going to make much difference at all. And... it would be really simple to run 2 back-to-back tests to see whether it actually matters or not.
That ReKnow is excellent! Just a little secret that we used back in the day of racing Sears riding lawn mowers. If you weld a 1.5 to 2.0 inch adapter to the exit of a straight pipe and then a short radius 90 deg elbow aimed directly toward the ground it will sound about twenty percent quieter to passersby with almost no back pressure. Some of the sound waves reflect off the heel of the elbow and cancels the emerging sound waves and the ground absorbs and deflects some of the rest. Still loud but very cheap and less offensive to none car-person's ears.
Fantastic work ! Love the CVT i had a Volvo 340 auto years ago and that was good while it lasted , What's the final drive / Diff ratio on the Renault ? , I am in the UK and look forward to watching Your videos Sunday evenings at tea time .
It'd be sick if you ran an AR500 or Eaton M90 blower on that 670cc or a 990cc later on, Holley Sniper EFI 1 or 2 bbl system run blowthrough would make it relatively easy.
I've seen some stuff about mufflers and for a performance muffler you want to expand the room for the exhaust to expand. So if you have a muffler that opens up to large chamber and ideally necks down to the size you need that's perfect for performance. Back pressure is just bad Information but a little isn't gonna be end of the world so if it's just a straight pipe exiting the muffler and it's not necked or flush with the body that's okay as long as there's room for the exhaust to expand and lose some pressure before it has to exit that's okay
Always great work and narration. Maybe in a future project you could take two v twins and make a v4. Several of those projects on you tube already, but would be neat to see the comparison between v2 and a v4 performance. Need to build a small pickup for a shop truck!!! Love the channel!!
Top spec 1300 Renault 10 european spec had 52hp and 17,9s (0-100kph). Renault did miracles with these 1289 engines... some say they had more real power than advertised... Would be really interesting to see this 1/2 size engine doing at least 0-60mph or 0-100kph in double of the time... good luck with your project!
I genuinely cannot wait until that "little" engine becomes a fire breathing high strung motor. Once it's going good, I propose a robot cantina road trip!
To all the people who heard “I can drive a manual without a clutch” you can, he’s right. But it will absolutely wear out the synchronizer rings inside the transmission if you’re not great at timing out when the engine and trans will match speeds. Clutch changes aren’t easy, but they’re way easier than taking the trans apart to change the synchros.
On a YT short comment, I managed to find like 4 or 5 people who claim that they do this on their 5 speeds all the time, and insinuated that I'm a noob for saying it's difficult. Chances of that being 0% aside, you definitely should not do this unless you have a particularly good reason to. Not only will you obliterate your synchros, your grampa style driving of repeatedly dumping 1000rpms in the middle of the road isn't fun for people behind you.
The secret to changing manual gears is matching the rpms of the input shaft to the speed of the desired gear. When you have a functional clutch, this is achieved by allowing the shaft to idle and letting devices known by a variety of names, within the transmission, synchronise the speed before allowing the gears to connect. (Look up synchromesh, synchroniser ring, dog clutch, cone clutch for explanation of how this works). Without a working clutch, it’s pretty easy to learn the rpms for a given road speed and match them up manually, leading to smooth changes, even when pushing on. The difficulty here is, with the cvt in the picture, you can’t directly control the input shaft rpm by altering the engine rpm. The cvt keeps adjusting the gear ratio constantly, trying to maximise efficiency and, while in neutral, trying to change manual ratio, there’s no load on the cvt and it’s trying to create one. The only time the cvt expects to have no load is when idling with a stationary output. With a rev on, or with rolling output, or both, it tries to get the best efficiency by adjusting the gearing, so you end up bashing the manual gears in, hoping for the best. That’s why it’s so slow and crunchy, when he’s doing that.
Could be fun to see you dig bit deeper into engine itself I'm sure you should be able to get your hands on some higher compression pistons that word fit it . Or port and polish the head with Dremel or something.
I just can't get over how this cute little thang sounds like an old chopper, hahaha. You could potentially lower the car a bit and possibly change the front to rear slant slightly to try to improve MPG as well.

@@TheStuartstardust Somebody took down my post. It's just a tube steel frame. I'm putting in the entire front end from about a 1968 VW bug with disc brakes and the engine will be an old Honda 500 V twin.
JIM! Get one of those old electric Citicars in disrepair and put a two-stroke in it! They don't rust all that bad because of a plastic shell and aluminum frame, so you can usually find them in decent quality, if you find one at all.
There are still people in this so-called enlightened world who don’t know a Manual transmission can be shifted sans clutch? Folks, do you think we truck drivers are constantly using the clutch for all the hundreds and sometimes thousands of shifts we make with our 10-, 12-, and 13-speed transmissions each day?? Why, our left calf muscles would be twice as thick as our right! 😳 Mine is only *slightly* thicker than the other. 😜
The clutch is already connected to the output of the CVT right? So replace the CVT pulleys and belt with a pair of sprockets and chain, no more CVT, it just transfers the power straight down to the CVT output shaft. Then you don't have to build a thrust bearing.
Thanks for that rear view mirror tease, and as I've said before, you aren't a bad looking dude and your channel isn't controversial, so I think your channel would be better with you on screen more. Also, an underbody panel would be aero without messing up the appearance, that should be a win-win. Thank you for the excellent content, as usual.
The staggered jetting maybe needed for the odd ball firing order on that V twin. The only reason they make any industrial engine a v twin is to make them more compact. The old opposed brigs was a much smoother more durable engine. But It was a flat head that ran dirty if they added overhead valves it would have become to wide to work for many industrial application's. So we have v twins. Some motorcycles still have them like Harleys but that's just for the image.
heh, something you said reminded me of a song, it goes 'let's follow the cops back home... and rob their houses'. a pictim from model-engine-ignition might be nice, help with the noise issue, i'm really only familiar with the regular tims, i was investigating for an ignition to put in a hitmiss motorbike, having a flight of fancy doesn't mean i'm dumb enough to actually do it.
If only I had the money to sponsor it, I'd like to see this guy's level of detail in everything done on a project with a salvaged sport-bike engine. (Since it's not about economy.)
What a ridiculous and fun way to waste some time and have some fun doing it. I love this idea and your use of a cvt is smart easy and cheap. That's a win, win, win in my book.
I said it on the 212 and I'll say it here too, a low restriction way to muffle sound is to simply put a turn in the pipe. A U bend will scramble up some of the sound waves and quiet it a lot more than you'd think but even a simple turn down toward the road after the muffler will effectively muffle sounds by using the ground to absorb some frequencies. I have a high revving high output 1800CC 4 cylinder car that's notorious for being very loud with essentially a straight through exhaust and it's not loud at all because the muffler I chose is a glass pack with a big U bend inside of it. All the flow, very little of the noise. For you, I think a 90 to the driver side, some pipe, then a 90 out the back would do nicely and give you AMPLE room to mount all the muffler you need and then some along the pipe. Sometimes simply stepping the diameter up and down can kill sounds too.
It’s turning out to be a fine lil build. 35+mpg in a cool oddball older lil car would be fun honestly. A/C would make it a perfect lil every day! It needs a TAC so you don’t over rev.
10:40 hey jimbo, there might be a cheap fix against your EMI problem. try out spark plugs with built in resistor or use one inline resistor on each spark wire. this limits the peak current wich is responsible for your EMI Trouble ;)
❤The twin cylinder Predator powered 'Reh-Nawlt'.. I'd say just go for efficiency, that'll improve both MPG and performance. Like upping the compression ratio on the engine 😃 Maybe overhaul the transmission too, to fix that reverse and improve any losses there... TBH i just really want to see this classic car be ACTUALLY USABLE heh 😉
I found on my 2000 Kawasaki ZR-7 (air/oil cooled 750), that when I fitted a 'Fuel' brand end can (had a Dynojet stage one kit in carbs), then when I had baffles removed yeah, she howled, but, when I had the baffles in, she had a deeper note, BUT, also 'Felt' smoother, more torque low down and just a generally nice ride... Underrated bikes them ZR-7s! 🤔😏 😎🇬🇧
Love it! This would be a good conversions for an original Fiat 500 (my first car)... but I'd really like to see what you do with a Predator engine and a junked Goldwing or Harley
Thanks Jimbo for another cool video. I can appreciate the amount of time you put into these videos, I'm guesing about a 50:1 ratio? Perceived exhaust sound is (of course) very hard to quantify on a video but, that's the best that can be accomplished with a TH-cam video. In trying to quiet down an air cooled engine over the years, it's a difficult task to be sure. Without a water jacket, the engine block rings with every detonation, not to mention the sound of all the reciprocating parts thrashing around inside the engine. One of the best ways to quiet the engine is to limit engine speed to basically a fast idle but, of course, there goes your power. Good idea to state which mods you will do and not do at the outset, thereby (hopefully) reducing the flood of well meaning modification suggestions.
I know you said no aerodynamic modifications, and I agree we definitely shouldn't ruin the classic appearance of this car, but... an undertray would definitely help the aerodynamics a lot and wouldn't affect the appearance at all. So maybe that? Improving aerodynamics is more than just fuel economy, it helps top speed a lot too!
People keep complaining about the CVT? I don't get it. My 2019 Insight has a CVT, gets better gas mileage than a car I know about that has a lawnmower engine and is about half the weight. Has twice the top speed and quieter too, but nevermind; thanks for the amusing content every Sunday morning.
Jimbo, it would be quite interesting to see what the acceleration numbers are for 100 and 200 meters. I don’t think Usain needs to worry about getting beaten by your little creation at 100 meters, but it still does surprisingly well for a lawn mower !! This Renault is a fascinating conversion …
Hey Jimbo, I get it, no aero mods, OK! Would dropping the car into the weeds for a really cool looking stance be a consideration? Not for the reduced frontal area to reduce aero drag though, but strictly for looks. Then you could try to avoid an an accidental fuel consumption comparison, or would you?
if nothing else, I love to look of a lowered car. I'm concerned about damaging the 54 year old suspension components and bushings if we start fiddling around under the car. some of the parts are a bit crusty.
After your monologue at the end there about how much you like the CVT, I can't help but chime in on it lol. The car it's attached to already has an off the shelf clutch system you could use. A motorcycle chain to a countershaft with a flywheel on it that will accept an OEM clutch would get your shift speeds way down. Shifts take forever the way it is now, and as you said, the CVT robs power. I don't think it would be significantly more complex to build than what you have now, and it may even end up coming out cheaper if you can source the clutch parts. Just some thoughts, and as usual, love the videos. I'll keep enjoying either way.
If your starter is strong enough, like on a Daihatsu Hijet weighing nothing with a 660cc motor; you can start in first gear without a clutch. I only know this because I snapped the clutch cable on a rock and drove around for a week without a clutch until the cable came in.
Comment for the algorithm and oddly I look forward to your videos each week more than anybody else video. I visit me Mum each Sunday too. I Post mine irregularly.
I think the fuel economy on this is better than the one on the original, umm, clone car. Yes, there was a clone of this, or white-labelling let's say. I can't upshift in all the gears on my 6-speed. I could, on an older 5-speed.
Hope you guys put in a stage 2 kit with a turbo in that 670. Always wanted to know what a built 670 in a small car would be like and how it would perform.
You know, I used to like you videos but lately they have been dragging.... do something interesting like taking out the internals and improving them to allow for more pressure/boost from a turbo or supercharger. Do what you want for your videos, its your channel... but this is from a long time viewer, some honest feedback.
Yeah, I think aero mods would be a waste of time on this car. Probably the only thing you could do, without drastically changing its appearance, would be a belly pan.
Have you thought about playing with the internals of the CVT to make it deliver the power more effectively, ie let the engine rev to its peak power before it starts it's shifting process, it's pretty common in the scooter world to have to change spring and variator weights after carb/ pipe modifications because it shifts where your engine makes peak power. CVT tuning is relatively cheap and could make a huge improvement
Love this channel! I'm curious how the engine temperature changes as you adjust A/F. I'd have to think its running under a higher load than intenteded?
So does the CVT act like a torque converter? I wonder if you put a bigger pully if it would get more torque? Kind of like changing gears on a bike having a bigger sprocket for more power and smaller for the get up and go.
I dont know much about cvt transmissions but when i was younger i had a scooter with the weights in the cvt. And it seems engine rpm is just dipping slightly when acceleration occurs in your video. Isnt it better to put in some other weights that will keep engine rpm at its optimal state of operation. Love your channel btw. Regards from The Netherlands.
Carburator spacers and Carburator black magics would be dank. Thermal isolation and a longer runner seems like a good start on engine. I'm personally interested in kohler k series single cylenders and the tractor pullers that use them in cub cadets rly rly hot rod those engines. A different cam grind might help with playing when the power come in too. In the 60's king midget micro cars used 12 and 14hp k series the 350 small block of single cylenders
My son-in-law had a carb on a 670 get gummed up with old fuel. Rather than rebuild it, he jury-rigged an old carb set up from an old 900cc motorcycle. WOW, did it bring that engine to life !
Fun. 😁 Don’t worry about haters. I spend a lot of time arguing both sides of a conversation(and winning) just to show my friends that there is no right or wrong, just what fits you or the situation. Enjoying this series.
Leave jets as they are now...port & polish the heads....hang a honda civic snail off of either cylinder and your golden...later if you want to drop some money into it look into aftermarket cams or have a machine shop mod the factory one(s) old school style
17:35 I made a whole video about that, explaining and demonstrating how to drive without using the clutch. Both going up and down the gears. Even how to set off without using the clutch in case you’re cable snaps or something. Nobody watched it though 😂

@@TheStuartstardust Somebody took down my post. It's just a tube steel frame. I'm putting in the entire front end from about a 1968 VW bug with disc brakes and the engine will be an old Honda 500 V twin.
JIM! Get one of those old electric Citicars in disrepair and put a two-stroke in it! They don't rust all that bad because of a plastic shell and aluminum frame, so you can usually find them in decent quality, if you find one at all.
😎 🆒️
There are still people in this so-called enlightened world who don’t know a Manual transmission can be shifted sans clutch?
Folks, do you think we truck drivers are constantly using the clutch for all the hundreds and sometimes thousands of shifts we make with our 10-, 12-, and 13-speed transmissions each day??
Why, our left calf muscles would be twice as thick as our right! 😳
Mine is only *slightly* thicker than the other. 😜
The clutch is already connected to the output of the CVT right? So replace the CVT pulleys and belt with a pair of sprockets and chain, no more CVT, it just transfers the power straight down to the CVT output shaft. Then you don't have to build a thrust bearing.
Thanks for that rear view mirror tease, and as I've said before, you aren't a bad looking dude and your channel isn't controversial, so I think your channel would be better with you on screen more. Also, an underbody panel would be aero without messing up the appearance, that should be a win-win. Thank you for the excellent content, as usual.
The staggered jetting maybe needed for the odd ball firing order on that V twin. The only reason they make any industrial engine a v twin is to make them more compact. The old opposed brigs was a much smoother more durable engine. But It was a flat head that ran dirty if they added overhead valves it would have become to wide to work for many industrial application's. So we have v twins. Some motorcycles still have them like Harleys but that's just for the image.
Keep it looking the way it is...hybridize it for mpg's. Turn it in to an...insight. Oh, never mind...
All jokes aside! This would be great around the town beater!
heh, something you said reminded me of a song, it goes 'let's follow the cops back home... and rob their houses'. a pictim from model-engine-ignition might be nice, help with the noise issue, i'm really only familiar with the regular tims, i was investigating for an ignition to put in a hitmiss motorbike, having a flight of fancy doesn't mean i'm dumb enough to actually do it.
If you want great MPG, get a small diesel. The early 2000s VW Jettas with their diesel will get 50 mpg on the highway.
Does anyone else feel nostalgia seeing that military windshield decal?
If only I had the money to sponsor it, I'd like to see this guy's level of detail in everything done on a project with a salvaged sport-bike engine. (Since it's not about economy.)
If only there were turbo busa motor somewhere.
@@schrodingersmechanic7622 Plenty of wrecked examples in junkyards around various military bases. Still kinda spendy though
What a ridiculous and fun way to waste some time and have some fun doing it.
I love this idea and your use of a cvt is smart easy and cheap. That's a win, win, win in my book.
Hey Jimbo, good video ! Return of the Drunken Gnomes ! Classic horror !
The motor is definitely falling off the cam at close to 50mph in 3rd. So when's the new camshaft going in?
You could also go in 1 without clutch if you stand still, you turn off the engine put it in 1 and start it
Excellent, drive around with a French licence plate for maximum authenticity!
Man i am glade that i found you when you where on the start of the 240cc supercharger concrete mixer engine been watching everything since then
What is going on in the four windows a video at the very end of the video?! Elaborate please Jimbo!
I still wanna see you add a scoop to the hood on the back, maybe with a cold Air intake to see if you can make more Power at "high" speeds
I said it on the 212 and I'll say it here too, a low restriction way to muffle sound is to simply put a turn in the pipe. A U bend will scramble up some of the sound waves and quiet it a lot more than you'd think but even a simple turn down toward the road after the muffler will effectively muffle sounds by using the ground to absorb some frequencies. I have a high revving high output 1800CC 4 cylinder car that's notorious for being very loud with essentially a straight through exhaust and it's not loud at all because the muffler I chose is a glass pack with a big U bend inside of it. All the flow, very little of the noise.
For you, I think a 90 to the driver side, some pipe, then a 90 out the back would do nicely and give you AMPLE room to mount all the muffler you need and then some along the pipe. Sometimes simply stepping the diameter up and down can kill sounds too.
It’s turning out to be a fine lil build. 35+mpg in a cool oddball older lil car would be fun honestly. A/C would make it a perfect lil every day! It needs a TAC so you don’t over rev.
10:40 hey jimbo, there might be a cheap fix against your EMI problem. try out spark plugs with built in resistor or use one inline resistor on each spark wire. this limits the peak current wich is responsible for your EMI Trouble ;)
❤The twin cylinder Predator powered 'Reh-Nawlt'.. I'd say just go for efficiency, that'll improve both MPG and performance. Like upping the compression ratio on the engine 😃
Maybe overhaul the transmission too, to fix that reverse and improve any losses there... TBH i just really want to see this classic car be ACTUALLY USABLE heh 😉
I also wonder if they have the alignment correct. Very small amount of toe error and mpg goes fast
More like Draino
I found on my 2000 Kawasaki ZR-7 (air/oil cooled 750), that when I fitted a 'Fuel' brand end can (had a Dynojet stage one kit in carbs), then when I had baffles removed yeah, she howled, but, when I had the baffles in, she had a deeper note, BUT, also 'Felt' smoother, more torque low down and just a generally nice ride... Underrated bikes them ZR-7s! 🤔😏
😎🇬🇧
Love it! This would be a good conversions for an original Fiat 500 (my first car)... but I'd really like to see what you do with a Predator engine and a junked Goldwing or Harley
It’s probably faster than a stock Fiat 500 …
Imagine what the Renault would weigh if it was 100% aluminum body........heck even coil springs these days can be lightweight composite materials.
Thanks Jimbo for another cool video. I can appreciate the amount of time you put into these videos, I'm guesing about a 50:1 ratio?
Perceived exhaust sound is (of course) very hard to quantify on a video but, that's the best that can be accomplished with a TH-cam video. In trying to quiet down an air cooled engine over the years, it's a difficult task to be sure. Without a water jacket, the engine block rings with every detonation, not to mention the sound of all the reciprocating parts thrashing around inside the engine. One of the best ways to quiet the engine is to limit engine speed to basically a fast idle but, of course, there goes your power.
Good idea to state which mods you will do and not do at the outset, thereby (hopefully) reducing the flood of well meaning modification suggestions.
I know you said no aerodynamic modifications, and I agree we definitely shouldn't ruin the classic appearance of this car, but... an undertray would definitely help the aerodynamics a lot and wouldn't affect the appearance at all. So maybe that? Improving aerodynamics is more than just fuel economy, it helps top speed a lot too!
A front air dam wouldn't hurt too
People keep complaining about the CVT? I don't get it. My 2019 Insight has a CVT, gets better gas mileage than a car I know about that has a lawnmower engine and is about half the weight. Has twice the top speed and quieter too, but nevermind; thanks for the amusing content every Sunday morning.
The only visual mod this vehicle needs is a little moustache between the headlights 👍.
Jimbo, it would be quite interesting to see what the acceleration numbers are for 100 and 200 meters.
I don’t think Usain needs to worry about getting beaten by your little creation at 100 meters, but it still does surprisingly well for a lawn mower !!
This Renault is a fascinating conversion …
Excellent presentation. Always enjoy them. Many thanks.
A carbon fiber teethpaste tube. I haven't worked the rest of the joke out yet.
Hey Jimbo, I get it, no aero mods, OK! Would dropping the car into the weeds for a really cool looking stance be a consideration? Not for the reduced frontal area to reduce aero drag though, but strictly for looks. Then you could try to avoid an an accidental fuel consumption comparison, or would you?
if nothing else, I love to look of a lowered car. I'm concerned about damaging the 54 year old suspension components and bushings if we start fiddling around under the car. some of the parts are a bit crusty.
After your monologue at the end there about how much you like the CVT, I can't help but chime in on it lol. The car it's attached to already has an off the shelf clutch system you could use. A motorcycle chain to a countershaft with a flywheel on it that will accept an OEM clutch would get your shift speeds way down. Shifts take forever the way it is now, and as you said, the CVT robs power. I don't think it would be significantly more complex to build than what you have now, and it may even end up coming out cheaper if you can source the clutch parts. Just some thoughts, and as usual, love the videos. I'll keep enjoying either way.
I like the sound of the "stupid carbon fiber" exhaust the best.
If your starter is strong enough, like on a Daihatsu Hijet weighing nothing with a 660cc motor; you can start in first gear without a clutch. I only know this because I snapped the clutch cable on a rock and drove around for a week without a clutch until the cable came in.
Comment for the algorithm and oddly I look forward to your videos each week more than anybody else video. I visit me Mum each Sunday too. I Post mine irregularly.
Wow, thank you!
Great fellowship and worship service pastor! whoops, wrong channel LOL... Great lesson RC! I love that ugly car!
I think the fuel economy on this is better than the one on the original, umm, clone car. Yes, there was a clone of this, or white-labelling let's say.
I can't upshift in all the gears on my 6-speed. I could, on an older 5-speed.
WHO CARES if HOLLLLYWOOD IS on STROKE if we can get good videos and talent like this? Man, this man has talent.!!!
Hope you guys put in a stage 2 kit with a turbo in that 670. Always wanted to know what a built 670 in a small car would be like and how it would perform.
Cars and Cameras drag rail?
You know, I used to like you videos but lately they have been dragging.... do something interesting like taking out the internals and improving them to allow for more pressure/boost from a turbo or supercharger. Do what you want for your videos, its your channel... but this is from a long time viewer, some honest feedback.
Been watching since you started the 212 content, maybe the 3rd episode. Awesome to see the projects progressing as fast as they do!
Yeah, I think aero mods would be a waste of time on this car. Probably the only thing you could do, without drastically changing its appearance, would be a belly pan.
Thank you Jimbo another awesome video!!!👍😸
Have you thought about playing with the internals of the CVT to make it deliver the power more effectively, ie let the engine rev to its peak power before it starts it's shifting process, it's pretty common in the scooter world to have to change spring and variator weights after carb/ pipe modifications because it shifts where your engine makes peak power.
CVT tuning is relatively cheap and could make a huge improvement
Love this channel! I'm curious how the engine temperature changes as you adjust A/F. I'd have to think its running under a higher load than intenteded?
lol, we haven't checked the cylinder head temp yet.... usually that is the first gauge I put on one of these little air cooled engines.
I've been following along with this build, but I may have missed something. What happened to 4th gear? Is there a reason you aren't using it?
Next up, a chinesium turbocharger from HF.
So does the CVT act like a torque converter? I wonder if you put a bigger pully if it would get more torque? Kind of like changing gears on a bike having a bigger sprocket for more power and smaller for the get up and go.
I dont know much about cvt transmissions but when i was younger i had a scooter with the weights in the cvt. And it seems engine rpm is just dipping slightly when acceleration occurs in your video. Isnt it better to put in some other weights that will keep engine rpm at its optimal state of operation. Love your channel btw. Regards from The Netherlands.
Fuel Economy and Aerodynamics aside… I think REVERSE should take priority. 😉
Carburator spacers and Carburator black magics would be dank. Thermal isolation and a longer runner seems like a good start on engine. I'm personally interested in kohler k series single cylenders and the tractor pullers that use them in cub cadets rly rly hot rod those engines. A different cam grind might help with playing when the power come in too. In the 60's king midget micro cars used 12 and 14hp k series the 350 small block of single cylenders
My son-in-law had a carb on a 670 get gummed up with old fuel. Rather than rebuild it, he jury-rigged an old carb set up from an old 900cc motorcycle. WOW, did it bring that engine to life !
Fun. 😁 Don’t worry about haters. I spend a lot of time arguing both sides of a conversation(and winning) just to show my friends that there is no right or wrong, just what fits you or the situation. Enjoying this series.
Leave jets as they are now...port & polish the heads....hang a honda civic snail off of either cylinder and your golden...later if you want to drop some money into it look into aftermarket cams or have a machine shop mod the factory one(s) old school style
Install an EFI and a catalytic converter.
Fooling around with engines is fine but keep the environment safe too.
A cat won't take down the power
How much does a catalytic perverter cost for an application like this ??
The engine just sounds like a Harley Davidson Sportster even without a muffler!
Don't modify the aero, except a chin spoiler under the front bumper would do wonders at highway speeds. 😆
17:35 I made a whole video about that, explaining and demonstrating how to drive without using the clutch. Both going up and down the gears. Even how to set off without using the clutch in case you’re cable snaps or something.
Nobody watched it though 😂
Just don't do any high speed runs north on Haven Road, I heard it's a speed trap around the high school. I want to see a run to the Carriage Crossing for a cinnamon bun, you can park out back with all the tractors...
The magneto on my Dad's old John Deere would raise hell with TV reception in my neighborhood in the 70's.
