When Google was young they used to say "Don't be evil", you say you won't go over to the dark side but as soon as you get rich and famous you'll change too! You'll start putting lawnmower engines in Maserati's and Ferrari's, just wait. I really enjoyed this video, Sundays wouldn't be the same without Robot Cantina, great dedication.
It simply amazes me that with all of the performance modifications done to this car through some miracle the exterior paint somehow manages to still be adhered to the car!
@@camino6431 Unlikely to add much performance through a different exhaust system other than going equal length. There isn't anything particularly restrictive about the thing. It's just the sound from an x-pipe that would be utterly ridiculous on a little lawn mower engine like that lol. The individual carbs are already overkill for practically anything, but they should help with response as you have less vacuum from the top of the intake valves to the throttle body (carb). The one thing I can think of that could be of use would be to run the air filters for the carbs to a different location where they get more cold air and less hot engine bay air. Maybe a metal heatshield to cover the header and running the filters to the back of the windshield would help. After all, the lack of efficiency is why engines like these never make much power to begin with since more fuel goes to heating up the engine rather than making more power. Doesn't matter for a lawnmower where your main concern is having it be cheap enough, but if you want perfromance then it's something to keep in mind.
You know, I used to drive a 1997 Subaru legacy outback that had piston slap in cylinder 2. You could hear it tapping at anything under 1100 revs. It made that sound the whole time I drove it. It gave me 98,000 leisurely trouble-free miles. Great car.
Yay! I got to see Robot Cantina & the famous genius Jimbo before breakfast & church! Now, I can concentrate on the sermon without distracting thoughts of a small chunky french car!
To his credit, I must point out that JimBo recently educated this long-time shade-tree mechanic that 16mm was equal to 5/8". Instead like a dope I paid Righteous Buck$ for a 16mm wrench some years ago, and have never used it again. BUT, it will save me replacing my broken 5/8" wrench now!
Thanks Jimbo for an interesting ride with this Renault project, I look forward to seeing what you’re gonna come up with as the next project. Mike from Montreal.
These projects are utterly ridiculous and pointless, and I absolutely LOVE them! I watch every episode with interest and have been watching since the start. Jimbo, you deserve every bit of success that comes your way. So I suppose they're not pointless if they're entertaining weirdos like me!
I just noticed that using the CVT clutch behind the Predator engine makes the Renault shift like an EV conversion that uses a manual transmission as part of the drivetrain. Transmissions are commonly used on low voltage settups (less than 180V) where the motor rpm can't go high enough to reach freeway cruising speeds if the gearing was setup for optimal acceleration. These cars are driven similarly to the Renault except that the acceleration gear is usually 2nd and the speed gear is usually 3rd. And you could drive the car in third, or even 4th all the time if you were willing to live with the less than stellar acceleration. It's a curious coincidence that two very different drivetrains could act the same way.
Great video! I wouldn't see a problem reusing the metal gaskets. I would anneal them before reuse though. Have you figured out a heater for winter driving? I imagine it's not the worst car in the snow. Like the old Bug, it should be decent I would think.
A group of scientists conducted a study to figure out why crows often manage to avoid being hit by cars but still sometimes end up as roadkill. They observed that crows are incredibly smart birds, able to work together and communicate warnings when danger is near. In fact, when they see a car approaching, the lookout crow always caws loudly, alerting the others to fly away just in time. But, after months of research, the scientists discovered the problem: crows can say “Caw! Caw!” to warn about American cars… but none of them know how to say “Renault!”
I just found your site. I love how you’re “restoring” that car. I’ve loved the look of it since I first saw one in The North Avenue Irregulars, it was being used by some bad guys.
Very nice...she is back on the road and not drooling all her oil out... Very cool...definitely a pretty cool little in town "grocery getter" if you ever needed just to tool around in a car/4 door go cart I wonder if this type of build would work on an old clapped out old school jeep or old ranger...just to have a vehicle to putz around in So awesome! Keep em coming!!!!
Hi Jimbo For what it’s worth, 70mph would have been a perfectly respectable top speed for such a car, as it left the factory. If you envisage going much faster, you really need to invest in suspension and brake performance modifications, similar to those available at the time. I bet you never thought you’d need to consider that, with your lawn mower motor modifications.
That thing sounds amazing. No wonder it turns heads. I know you're keeping it all low buck, but again, I couldn't help but put some love on this thing. It's not butt ugly!
This always makes my sunday evening great!! Haven't even seen it yet. This comment is only a support for uncle Jimbo's channel. He deserves all the views in the world!!
Hi Jimm. Am in love with the renault project. I am almost willing to bet there are a lot of people out here in youtube land wanting to see a speed test with you shifting through the gears in the manual box !!! PLEEEAASE !!!
I love wacky French cars, and adding a drive train that was never intended for road use just makes me love it more. I'd daily drive that thing. In good weather only of course.
Any time you're thinking of how mediocre any car is, stop on the side of the road and get out and walk. Cars are time machines. For anyone who's ridden a horse, the same applies. You'll feel small and insignificant. Wonderful little machine you have there. Of course, I had to subscribe. Cheerio, mate!
There's about 12"difference in pipe length, so there is not much chance the cyl tunes are going to be the same, ie, the harmonics won't happen at the same rpms. Had a customer design his own exh too long, and on the dyno the individual carbs had a fuel cloud form in front of them in mid air due to fuel stand-off, ie, the exh pressure wave is 50 times stronger than piston demand so it can push the mixture out the carb.
At lower revs later inlet valve closing can also push charge out of the carb. Say you have a cam set up for high revs, with the inlet closing 60 degrees after BDC. At low speeds the flow will actually stop, reverse and start going back out of the cylinder before the valve closes.
I love the R&D you've shown us here. It has been extremely inspirational. I have wanted to create a range extender for cheap used 1st gen EVs like Nissan Leaf, Focus EV, 500e, Smart EV, iMiEV, Spark EV, ect where a reciever hitch is mou ted on the back with a 5th wheel mounted on a hinged arm with a coilover for damping and articulation, powered by an engi e like this. Its only job would be to maintain steady speeds on mainly level ground, accelleration, in town, traffic would all be electric and any steep hills at higher speeds the electric drive could again step in. It would essentially trick the ev into thinking it is coasting. Its a perfect job for a small engine like this, all accessories are handled by the car electrically, all the power can be aplied directly to this 5th wheel behind it. I would say that even if only 30-50mpg was possible depending if you are cruising at 45mph or 80mph, the rare occasion ypu wpuld need to go a cpuple hundred miles in a day on the highway or B roads, the cost and convience is totally worth it. Of course to make a contraption like this worth it, you would probably need to keep the price down to a couple thousand dollars at most, then add a $2000-5000 old EV with 45-70miles of range. It would be a good alternative to people who cant afford a new $35,000+ automobile for basic subsistance uses and they can't afford to drive a cheap but bulletproof old truck or car around that gets 8-12mpg either. This research is great and I think that there could be a few people out there turning these engimes into transportation.
I like the exhaust mic! It's like the microphones they put underneath the wrestling mats on tv to make it sound like someone had a really hard landing haha
Although it probably won't happen I would love to see a cross over vid with Greg from red beards garage, not for all out power but i bet he could help with tuneing for better low end torque and help with better rods ,valve springs and camshaft...oh and a flywheel that doesn't shatter if you over rev it .

I'm driving down the East side of Iowa today with the best Iowa corn fed beef in the Universe! If I still lived on the West side of Iowa I would stop and wave to the gnomes today! Good luck and God's speed brother from another mother!
Nothing wrong with a "Because I can" sort of project. You never know who will be inspired by a project such as this. I wish I could ride along sometimes and just get a better feel of the acceleration. I imagine this would be an OK in-town rig.
I like the demonstration of modifications, your experimentation could save others time and money. I remember about when gas got crazy, someone took a 1 st gen Mazda RX-7 with toasted engine and installed similar Kubota 3 cylinder diesel. He had inline setup similar to yours and went through process of getting to turbo, 30+ mpg. Used as daily commuter. Would be cool if could be able to adjust timing, adjustable keys is it. I have installed MSD 5 box on old gravely lawnmower, about 40 years ago and wondered about use of MSD ignition timing adjuster, since it used auto ignition coil. Dump clutch, would leave rubber patches.
For assembly lube you ought to try what shops used to use back in the day, Vaseline. It's pure petroleum jelly and will react with very little if anything in the engine. It's closer to being a soft grease but without all sorts of additives mixed into it, it will dissolve in oil and gasoline will strip it with no issue whatsoever if you need to remove it from your parts for some reason.
13:24: vacuum guages not needed: make sure both throttle slides are bottomed-out - then take up cable slack on both (just like you did) until slide just starts to move, but not quite
You could install a small cable operated disc brake system on the input shaft of the transmission to stop the rotation for the initial shift into gear, put the break lever on the shifter.
a trick i read about a long time ago in hotrod magazine was to keep gaskets for holley double pumper carbs from tearing (think these have glue on both sides) , the trick was to coat one side with chapstick , seems the cherry flavour was best
Honestly most of the cost these days is probably in engineering the crash safety and emissions. Can't really skimp on those in a modern context. All the silly electronic gizmos are a small fraction of the cost of a new car.
WooHoo, c´mon, We can crack 70! I think the Renault was to top out at around 120km/h anyways so You´re so close… I think new shocks would do Yous well. Just take the cheapest that fit- for science. But I think that would help make the wheels feel more like …wheels. I love the Honda Diesel- what a lovely car it became. Kind Regards
a simple way to balance carbs with 1 into 2 throttle cable is a drill bit just under the slide on both carbs and a ruler this allows you to see if the slides are in sync and adjust as needed
I have a project that I will be starting soon as I get situated with the care of my elderly mother. Going to be building a 2 stroke racing lawnmower with a 50 cc scooter engine have all kinds of modifications that are going to perk it up... 😮😮😮 LoL 😆
Congratulations! You've successfully converted a Renault into a "half engined" soviet ZAZ (aircooled V4 pushing in the beginning something looking like the original FIAT 600, and later on similar to this Renault sized and looking cart with stolen from german NSU Prinz 4 looks) :) Your contraption seems more powerful than soviets' one, though.
It's an old hot rodders trick to flip pistons. Sometimes you run into a little piston slap until an engine is up to temp, depending on the engine. While I agree it may cause some premature wear there is some torque to be made by changing the angle of the rod vs crank
If it's unstable at speed, I'd check for lash in the steering box (or equivalent), see if any bushings are worn out, and maybe look into shocks and struts! For such an old car I doubt the parts are readily available, but it could be a fun episode to see what kind of difference it could make to your driving experience. Maybe put it up on Jack stands and see what the steering does before and after, and do some of those snakey turns on the road to see body roll and all that.
@@robotcantina8957 Oh, I guess you've already researched those components? That's unfortunate... Still, if you ever get any hits on those parts, I'd love to see some kind of update on it in the future!
Beware that offset woodruff keys exist for the specific purpose of advancing the static ignition timing of the engine. Used often in karting with the GX series engine but they exist for these engines as well. As for the weaving nature of the car at speed: align the front suspension to give it more caster than whatever it currently has, and make sure the front has some toe IN (not out) for highway speed stability. This is counter to what most would do for performance but it will surely help in case of this car.
@@robotcantina8957 You might have luck trying one for the GX390 as they are essentially the single-cylinder version of the 670 and the keyways should be nigh identical between them.
I’m planning on fixing two F-zero bike frames together, using a timing belt to connect the steering to a central wheel, making a central carriage with a mower seat and springs, put the 420cc underneath with a series 40 torque converter run into a 3 speed peerless transmission for rear wheel drive. Use 115/70r 15s for tires.
Spray headliner adhesive or spread Edelbrock Gasgasinch on one side of the gasket and the surface it mates to, then seat it. Then grease the other side. What I did for years on Chevy V8 valve covers that were frequently removed for adjusting solid lifters. Glued the gaskets to the valve covers and greased the head side. Works like a charm.
The ports on that cylinder head does not appear "strangled". Opening up the ports overall diameter only makes a difference high up in the rpm band (tuned reflected pulse physics). Smaller ports produce better port velocity and VE at lower rpm. The Renault has turned into a very unique car with a very unique sound.
I can see more speed and better fuel economy coming soon! a couple of side air intakes feeding those carburettors (air fed from a non-heated source + some free ram-air charging effect) plus a lid stuck on the engine bay for better aerodynamics. note 1: those who use no assembly lubrication rely on the farce, may the farce be with them! note 2: the 9mm wrench was designed to be beaten onto a rounded 3/8" (9.5mm) head 😁
Howdy, many of the new polaris ATVs and side by sides have a bearing on the primary clutch that the bottom of the belt rides on, this allows you to run a tighter belt without the secondary spinning at idle, if you could incorporate this, you may have a better shifting trans at idle.
Project is coming up nicely. Your O2 sensors should be at least 12 to 18'' away from the engine to allow the exhaust gasses to mix together vs near the engine. It will not give you an exact ratio that close.
Instead of 'fast' and 'faster', it needs to be a Turtle and Rabbit Icon. It IS a lawnmower engine afterall..
after all*
It's not one word.

@@nvcnc It is probably also lead bearing.
Those ports are great! Large, "tunnel" shaped, and matched perfectly to the gasket with appropriately polished surface.
That was my thought, like damn they already port matches and look smooth if not polished finish 🤔.. killer work for stock 😅
That thing definitely sounds sporty roaring down the road! Sounds faster than it is.
You have individual carbs, now all it needs is individual exhausts :). Imagine that little cheap turd engine with an x-pipe going out both ends lol.

I’d like to see the performance with 4 people in the car.
NEXT EPISODE stay tuned!
I'm driving down the East side of Iowa today with the best Iowa corn fed beef in the Universe! If I still lived on the West side of Iowa I would stop and wave to the gnomes today! Good luck and God's speed brother from another mother!
Knock knock, I just wanted to klick on the Like button but for some reason it seems I already did it in the first minutes of the video.
Nothing wrong with a "Because I can" sort of project. You never know who will be inspired by a project such as this. I wish I could ride along sometimes and just get a better feel of the acceleration. I imagine this would be an OK in-town rig.
I know I’m sad but I do luck forward to my Sunday cup of tea,and seeing how the Renault is doing,keep them coming please,thanks .
I like the demonstration of modifications, your experimentation could save others time and money. I remember about when gas got crazy, someone took a 1 st gen Mazda RX-7 with toasted engine and installed similar Kubota 3 cylinder diesel. He had inline setup similar to yours and went through process of getting to turbo, 30+ mpg. Used as daily commuter. Would be cool if could be able to adjust timing, adjustable keys is it. I have installed MSD 5 box on old gravely lawnmower, about 40 years ago and wondered about use of MSD ignition timing adjuster, since it used auto ignition coil. Dump clutch, would leave rubber patches.
You were the chosen one! You were suppose to not play with the Subaru, not join them!
Hell yeah, that new exhaust mic placement is great. Also love the "fast" and "faster" transmission graphic lol.
Best video yet, Jimbo! Thanks a bunch.
For assembly lube you ought to try what shops used to use back in the day, Vaseline. It's pure petroleum jelly and will react with very little if anything in the engine. It's closer to being a soft grease but without all sorts of additives mixed into it, it will dissolve in oil and gasoline will strip it with no issue whatsoever if you need to remove it from your parts for some reason.
Excellent work and great results.
Another great Sunday morning! Hope you are doing well jimbo!! The Renault is coming together nicely
13:24: vacuum guages not needed: make sure both throttle slides are bottomed-out - then take up cable slack on both (just like you did) until slide just starts to move, but not quite
I mentioned that it took a while to synchronize the carburetors. Getting the idle to synchronize really did require the vacuum gauges.
You could install a small cable operated disc brake system on the input shaft of the transmission to stop the rotation for the initial shift into gear, put the break lever on the shifter.
"It would be a miracle if something inside the crankcase didn't get splash lubricated" Well said, Jimbo.
I love her vids. I look forward to watching them every Sunday. Thank you, sir.
VW used a 9mm 12 point for the pressure plate bolts. That's a rare one! Like GM using the 5.5mm for the ignition modules in HEI distributors...
Ford used 5.5mm for a lot of Super Duty grille bolts. My 1999 F250 and 2005 F350 used them.
Thanks Jimbo. I Love every weeks adventures regardless of the car involved. Keep up the entertaining work. Thanks, Morty. 😁
3:27 I was already subscribed and felt compelled to like, it works Jimbo!
a trick i read about a long time ago in hotrod magazine was to keep gaskets for holley double pumper carbs from tearing (think these have glue on both sides) , the trick was to coat one side with chapstick , seems the cherry flavour was best
Nice work and great ingenuity. Goes to show how simple things can be.
If cars were less sophisticated we would have more in our wallets.
Honestly most of the cost these days is probably in engineering the crash safety and emissions. Can't really skimp on those in a modern context. All the silly electronic gizmos are a small fraction of the cost of a new car.
WooHoo, c´mon, We can crack 70! I think the Renault was to top out at around 120km/h anyways so You´re so close… I think new shocks would do Yous well.
Just take the cheapest that fit- for science. But I think that would help make the wheels feel more like …wheels.
I love the Honda Diesel- what a lovely car it became. Kind Regards
a simple way to balance carbs with 1 into 2 throttle cable is a drill bit just under the slide on both carbs and a ruler this allows you to see if the slides are in sync and adjust as needed
Its about time you put some variable ignition timing on this engine, with some nice oversize coils and pulstar plugs. ;-)
I have a project that I will be starting soon as I get situated with the care of my elderly mother. Going to be building a 2 stroke racing lawnmower with a 50 cc scooter engine have all kinds of modifications that are going to perk it up... 😮😮😮 LoL 😆
Congratulations! You've successfully converted a Renault into a "half engined" soviet ZAZ (aircooled V4 pushing in the beginning something looking like the original FIAT 600, and later on similar to this Renault sized and looking cart with stolen from german NSU Prinz 4 looks) :) Your contraption seems more powerful than soviets' one, though.
Looks like a good little car for puttering around town.
It's an old hot rodders trick to flip pistons. Sometimes you run into a little piston slap until an engine is up to temp, depending on the engine. While I agree it may cause some premature wear there is some torque to be made by changing the angle of the rod vs crank
If it's unstable at speed, I'd check for lash in the steering box (or equivalent), see if any bushings are worn out, and maybe look into shocks and struts! For such an old car I doubt the parts are readily available, but it could be a fun episode to see what kind of difference it could make to your driving experience. Maybe put it up on Jack stands and see what the steering does before and after, and do some of those snakey turns on the road to see body roll and all that.
I'm afraid that taking the front suspension apart would likely take weeks or months to repair the suspension.
@@robotcantina8957 Oh, I guess you've already researched those components? That's unfortunate... Still, if you ever get any hits on those parts, I'd love to see some kind of update on it in the future!
Beware that offset woodruff keys exist for the specific purpose of advancing the static ignition timing of the engine. Used often in karting with the GX series engine but they exist for these engines as well.
As for the weaving nature of the car at speed: align the front suspension to give it more caster than whatever it currently has, and make sure the front has some toe IN (not out) for highway speed stability. This is counter to what most would do for performance but it will surely help in case of this car.
I have uses offset keys in the past on smaller engines, however I haven't found and offset key specifically for the 670 yet.
@@robotcantina8957 You might have luck trying one for the GX390 as they are essentially the single-cylinder version of the 670 and the keyways should be nigh identical between them.
I’m planning on fixing two F-zero bike frames together, using a timing belt to connect the steering to a central wheel, making a central carriage with a mower seat and springs, put the 420cc underneath with a series 40 torque converter run into a 3 speed peerless transmission for rear wheel drive. Use 115/70r 15s for tires.
I find your videos really educational and entertaining to watch
Spray headliner adhesive or spread Edelbrock Gasgasinch on one side of the gasket and the surface it mates to, then seat it. Then grease the other side. What I did for years on Chevy V8 valve covers that were frequently removed for adjusting solid lifters. Glued the gaskets to the valve covers and greased the head side. Works like a charm.
Amazing! I'm currently working on rebuilding a Renault 11 engine
The ports on that cylinder head does not appear "strangled". Opening up the ports overall diameter only makes a difference high up in the rpm band (tuned reflected pulse physics). Smaller ports produce better port velocity and VE at lower rpm. The Renault has turned into a very unique car with a very unique sound.
I can see more speed and better fuel economy coming soon! a couple of side air intakes feeding those carburettors (air fed from a non-heated source + some free ram-air charging effect) plus a lid stuck on the engine bay for better aerodynamics.
note 1: those who use no assembly lubrication rely on the farce, may the farce be with them!
note 2: the 9mm wrench was designed to be beaten onto a rounded 3/8" (9.5mm) head 😁
Howdy, many of the new polaris ATVs and side by sides have a bearing on the primary clutch that the bottom of the belt rides on, this allows you to run a tighter belt without the secondary spinning at idle, if you could incorporate this, you may have a better shifting trans at idle.
Project is coming up nicely. Your O2 sensors should be at least 12 to 18'' away from the engine to allow the exhaust gasses to mix together vs near the engine. It will not give you an exact ratio that close.
