it doesn't run backwards because of the spark timing, I'm not sure if there's many two strokes that really do run backwards anyways, because the timing is usually set forwards a little.
Depends on the cam lobe running the points. Old Harley davidson golf carts were made to run backwards, and they had a symmetrical lobe. Tricky to get them timed right both forward and reverse tho.
As they were trying to start it backwards I was screaming at my tv. Timing! Lol. Some two strokes are symmetrically timed. This may be by coincidence or by design on some of them.
The old detroit diesel 2 stroke truck engines would run back words. I saw a guy stall one about 100 ft ahead of me on a dirt haul job. He rolled backwards let the clutch out, It started up and smoke was pouring out of the air cleaner and he could not figure out why he only had 3 forward gears and 13 reverses LOL. Yes he as well as the truck I was driving had 13 speed transmissions. 13 forward 3 reverse
@@chib9427 o um ok. 2 stroke diesels will not run worth a shit, if at all backwards. Let alone trying 3 gears one direction and 13 another. I call bs old boy story.
Had a Mercury Mark 78 and a 700 that worked that way, two. It was a distributor and you could see it twist around when you pulled the throttle rearward to start it in reverse. Royal PIA compared to a transmission, though.
@@n3glv harley davidson golf carts did that by having a symmetrical lobe that runs the points. Very easily achieved without complex mechanisms to change the timing. Think about how points work, they fire when opening. When points close is when it will fire in reverse rotation.
Have one their awesome engines, made by Fuji Industrial they are also the same engine's used by Polaris the 244cc or sometimes called their 250s ccs. I have a Polaris connecting rod Hot rods Rod a cylinder off a 488cc Polaris and piston from a 244 as well as a head. The parts bolt right onto the Ezgo crankcases, only modification was longer studs for the cylinder to block. Using the stock Polaris 488 38mm slide carb and a expansion pipe and full exhaust off a 250 atv. I ended up putting it in a newer version Ezgo TXT with F-N-R rear end to do away with the running backwards felt it would have a stronger spark if it was only firing once so I removed the reverse bump off the reluctor ring on the flywheel. Otherwise she's probably every bit of 30hp from a Ezgo engine now, just wanted to share.
With the amount of old stuff you guys tear apart, you should get a proper scalpel, couple of hole-punches and some gasket material. Cut up paper milk cartons also work for most gaskets on these kind of engines in a bind.
The best material I've found is the flimsy pizza 10" boxes that a slice would come in. They are impregnated with clay and work great. But cereal boxes and pretty much whatever non corrugated cardboard work fine.

Mercury had “ direct reversing in their outboards in the 1950’s. You would shut the motor off, flip a switch, and it would start the opposite direction for reverse. Also some 2 stroke golf carts did the same thing for reverse.

Oh man! Those rims are the best ones I've ever seen! I know somebody out there can redo that. They may be worth fixing and re-chroming. They remind me of those Harley-Davidson 5 spoke rims from the 70s

That's a bunch of boloney...modern oils are far superior to the oils that were available when old 2 strokes called for such rich ratios like 32 or even 16:1. Up until the 80's there weren't even many dedicated "2 Stroke Oils", you'd just use plain SAE30 motor oil. 50 or 40:1 is perfectly fine in older stuff as long as you use a quality oil.
I absolutely LOVE the look of this thing! The vintage/rat rod patina of the bike and the engine really ties it all together so nicely. The new chrome wheels don't even look out of place! I'd suggest spraying the whole thing as-is with some matte clearcoat just to preserve the patina, and so it won't rust any worse. I'm sure with a few tweaks, you could probably get a little bit more pep out of it, too!
For a two-stroke to operate in reverse you have to adjust the timing. Because the timing does not spark at top dead center it's right after top dead center. The knocking sound when you move the crank and flywheel is the bearings on the piston and the crankshaft are worn out. I wouldn't run it very much longer without getting the bearings replaced. All I'm making photo neutralized the reason the carburetor is on the crank housing is because when the Piston moves up it sucks air and fuel in, and when the Piston moves down it acts like a supercharger/compressor forcing the Reed valves to close, and it compresses until the Piston moves down below the intake port on the cylinder head. The compressed air and fuel forces the exhaust out with the fresh charge.
@@cheerdiver I've been working on all types of small engines for over 50yrs. Janson engine were known to be use on large chainsaw clean back the 1930s and I believe some loggers still use them Dennis from Delaware
2 stroke Golf cart engines ran both ways to simplify the transaxle....no need for a reverse gear. They have "zero timed" ignitions....no advance. As such...they ran ok...but never great. But they did run both directions! Win for IKE !
Would definitely run a 20:1 or 30/32:1 mixture in that the way the crankcase is only premix lubricated. Heck I run 32:1 in all my two smokers except my old case reed dirt-bikes from the 70s, factory recommended mixture for my 70s 2smokers is 20:1 for longevity of the rod/crank, needle bearings & wristpin. P.s. ignition timing is way retarded running it in reverse (since it's advanced running forwards), you'd have to relocate the pickup or re-clock the magneto to compensate.
I think John is fading from the camera and is transitioning to back office behind the scenes type stuff … see him less and less and it makes sense they brought Charles on board to replace him eventually …. I love Charles … love Isaac… love John too and I’m sure going to miss him if that’s the case … i remember this channel when they first started working on go karts …. I miss the small channel days
That was exactly my thought the ignition was probably set before top dead center. Running the engine in reverse would have the timing extremely retarded.
The old mercury 6 cylinder outboards, as well as the 1920's Elto Outboards could run backwards by just flipping the distributor/timer backwards. Our old Harley Davidson golf cart ran in reverse too.
You guys just always get into the projects I loved to work with as a teenager. Though DEFINITELY never had all the equipment or anything you guys put into stuff ! It’s just AWESOME ! I’m a 48 year old handicapped brain tumor survivor and can’t delve into that stuff anymore. Bringing my youth back !!! This is just great to bring back memories for MULTIPLE PEOPLE 😃
I'm 63 years old and I remember those wheels. We didn't like them because the tires weren't available like the standard mini bike wheels. Yes 2 strokes will run in reverse. The Fairmont track inspection cars (think the old pump handle railroad cars like you see in the old western movies, only with a motor) have a 2 stroke motor on them that by moving the timing will run in reverse. I have a friend that has one and being the crank hole is on my side it's my job to spin it over. Whichever way the operator wants it to go. My friend says I'm the most reliable starter motor he's ever had.....LOL! I like the look of the bike. Jacobson made mowers mostly so that motor likely came from a reel type mower. If you can get that motor up on the RPM's is might be pretty strong. Cool build. Cheers Terry from South Carolina
Jacobson is owned by Textron International they manufacture Golf Course Maintenance and mowing equipment. If you call your local Jacobsen dealer you might be able to find replacement parts for that
Man when I was a kid there was a western auto store they displayed a mini bike like that in the window with those same type of wheels back in early 80s
It was bound to happen, one day the three of you were going to build THE slowest mini bike in the Cars and Cameras inventory, congratulations! I think that it would be such fun, just really a blast working around the three of you, it would be just fantastic. I can't wait for the next video!
Ike! You are correct! Reverse on snowmobiles when activated changes ignition timing to run the engine backwards! It's very common on 2 cycles that need a simple reverse feature.
In theroy yes a 2stroke will run in reverse for example in some snowmobile engines to put it in reverse you hit a button which makes it run in reverse which in turn makes the snowmobile go in reverse but the magneto in some engines are directional and only work when the magnets pass by it in its intended operational direction.
Hey guys if I'm not mistaken Tecumseh made those motors for Jacobson. They are not a high rpm motor, as I remember 4200 was max rpm. It was great to hear that little beast run. Now back in the day it was this motor or it's bigger brother that were the competition for the Macs on the racing carts back in the 50s and 60s. I know this because my grade school friend raced gocarts in the mid 60s.
Love seeing you guys get into some vintage engines and bike builds! the engine is probably the same age as the bike. Jacobsen was originaly a mower company and had big crude two-stroke uprights up until they bought the pattern rights to the johnston utilimotor in the 20s. made by the same johnson that makes boat motors. that johnson utilimotor engine evolved into the engine you have after years of renditions. it would have been on probably a mower called a 4 acre since it has the big tank. not a go-kart motor or bike motor originally. they should make good power though if tuned right. the muffler is a stove pipe style muffler that would work best for power if the extra pipes are removed and more holes in the outer pipe there is a lot of restriction in them loosing power for quiet mowing. To save your old ignition coil id suggest not pulling the wire to kill an older motor as it can make the coil short internally. they also tend to have pinging noises do to how thin the cylinder is and most don't have needle-bearing wrist pins. the timing of the mag is timed earlier to help with better power. I've worked on all three engines from the early one, johnson, and the later ones. fun motors. if you have any questions or possible need any parts for one I do have some. i also have a lot of other odd engines on my channel if you want to look. love seeing the older builds keep it up!
I have used my wife's cricut cutter to make gaskets. Reassemble the torn gasket with tape the best you can, use a flatbed scanner and scan the gasket. Convert the scan to an SVG with Inkscape and then get the cricut to cut a new gasket out of gasket paper.
Back in the early 1970’s I owned several Yamaha 360 enduros. Many times when kick starting them hit would kick back (dangerous for legs ankles and feet) but it would start. More then a few times I would give it some gas and let the clutch out to be shocked it was running backwards. Another fun fact there were some Kawasaki 2 strokes that had the carb under a side cover Down in-line with the crank. The first time I saw one I thought it didn’t have a carb. Those were the days!! Lol
I used to ride with a guy that had trouble with his 2 stroke. When kick starting, usually, it would backfire and spin backwards. He was the only one there that had 6 gears in reverse! Lol. Thank for sending me back to a better time. :)
See if you could mount up a proper expansion pipe and silencer on there and that motor would run a whole lot better and make more power some new reeds and possibly a mikuni would help a whole lot too
Love the addition of Charles, and appreciate everything y'all do! Before a month ago I had zero working knowledge of small engines, now I have my own custom mini-bike largely thanks to the awesome content y'all put out! Keep it up!
The shot of the rotating assembly is considered as the primary compression chamber. There are transfer ports from the there (rotating assembly) to the secondary compression chamber (top of the piston). The exhaust should have fiberglass mesh. Certain snowmobile two strokes did run in reverse. The ignition timing and fueling was a bit different than this.
My dad had a 2 and 1/4 horse 2-stroke Jacobson lawn edger. I'm 58 years old and it was old when I was young it ran great the muffler was the engine running against the concrete it had a little rumble a very unique sound there was no muffler it just reverberated off the ground!
looking good! 2 things to suggest: 1- maybe try fiberglass to fix the holes in the rim?? 2- to align the sprockets, clamp a straight edge on the 2 sprockets and boom! aligned
Chances are, timing in one direction will be set slightly advanced; maybe 3 or 4 degrees. Running it backwards will definitely cause the spark to fire after TDC, 3 or 4 degrees. Some older two stroke diesels are set at TDC to run both CW and CCW. But your Jacobsen seems to be a lot newer, even being old, and probably won’t run both directions.
That bike is Old Skool Cool! I'm a big fan of 2stroke and if you can get it up into the power band I think you might find it could exceed a 6-8hp 4stroke.
At 14:20 removing float bowl de-laminates its seal. It's nigh impossible to re-seal, replace is best to stop inevitable leakage. Run in reverse only with timing change. Bravo for the rescue!
Being a old guy who used to play with those engines when they were newer. They are a bit noisy. Even the old dirt bikes. They also had a Clinton engine just like that one. 2.5 horsepower
There is a 2 stroke built by Villiers that runs in forward or reverse. I dont know the details but it was used in Pengor Penguin and Beaver amphibious atv`s. Reversing electric start determined which way the engine ran as this was the way these atv`s had reverse. Yup you shut off the engine, turned the key in the opposite direction of forward start and it reversed the current to the starter and cranked the engine backwards thus allowing a reverse "gear"..
After my countless number of hours spent on TH-cam, I’m surprised I’m just finding out about you guys now.. and am I ever glad I have! You guys are so likeable. No wonder your at a million subs already!
The three of you work together really well! Have you considered taking a rim and using your metal bender to make a steel hoop 'tire' for it? You could do one of your old experiment videos with leaving it plain vs knobs vs steel tread vs rubber tread vs bolts tacked on vs full Amish tractor steel blades, etc. Definitely would need to have front and rear suspension, as well as really good fenders though.

P.s. ignition timing is way retarded running it in reverse (since it's advanced running forwards), you'd have to relocate the pickup or re-clock the magneto to compensate.
Factory spec was with oils from 1960s. Running 40:1 with new oils is just fine, it's actually recommended so you don't run lean on gas.
I have one of these bikes and its about 80 percent original and its one fun bike.
Hearing John talk about “testosterone” and “the bedroom” felt… really really wrong lol.
Yeah he's like a cousin or something and testosterone talk feels weird! Sorry John
and this is why testosterone for men is in the toilet. Health is taboo apparently. We should be getting hormone check ups.
63 and bounce out of bed every morning.
It's a real issue for a lot of people
@@CarsandCameras I know it just felt strange coming from you guys lol.
Nice episode guys. Sweet little bike!
I think John is fading from the camera and is transitioning to back office behind the scenes type stuff … see him less and less and it makes sense they brought Charles on board to replace him eventually …. I love Charles … love Isaac… love John too and I’m sure going to miss him if that’s the case … i remember this channel when they first started working on go karts …. I miss the small channel days
I personally don't care for John .
@@larryalexander4833 I’m curious as to why? I have some thoughts but I’m not going to be rude on this channel.
Those old Jacobsen engines were way cool.
A 2 stoke cannot just be spun the opposite direction to run. It would need timing adjusted properly for the direction of rotation
That was exactly my thought the ignition was probably set before top dead center. Running the engine in reverse would have the timing extremely retarded.
@@rayoverstreet9254 most two-strokes can be started without adjusting the ignition, but some can be damn hard to start
The old mercury 6 cylinder outboards, as well as the 1920's Elto Outboards could run backwards by just flipping the distributor/timer backwards. Our old Harley Davidson golf cart ran in reverse too.

You guys just always get into the projects I loved to work with as a teenager. Though DEFINITELY never had all the equipment or anything you guys put into stuff ! It’s just AWESOME ! I’m a 48 year old handicapped brain tumor survivor and can’t delve into that stuff anymore. Bringing my youth back !!! This is just great to bring back memories for MULTIPLE PEOPLE 😃
Another great video guys. This Old Man enjoying every one. 🛵🧔💝💝💝
Jack shaft sprocket gear reduction. Eliminates the idler and gives more flexibility in gearing. Love it!
I'm 63 years old and I remember those wheels. We didn't like them because the tires weren't available like the standard mini bike wheels.
Yes 2 strokes will run in reverse. The Fairmont track inspection cars (think the old pump handle railroad cars like you see in the old western movies, only with a motor) have a 2 stroke motor on them that by moving the timing will run in reverse. I have a friend that has one and being the crank hole is on my side it's my job to spin it over. Whichever way the operator wants it to go. My friend says I'm the most reliable starter motor he's ever had.....LOL!
I like the look of the bike. Jacobson made mowers mostly so that motor likely came from a reel type mower. If you can get that motor up on the RPM's is might be pretty strong.
Cool build.
Cheers
Terry from South Carolina
Jacobson is owned by Textron International they manufacture Golf Course Maintenance and mowing equipment. If you call your local Jacobsen dealer you might be able to find replacement parts for that
Man when I was a kid there was a western auto store they displayed a mini bike like that in the window with those same type of wheels back in early 80s
It was bound to happen, one day the three of you were going to build THE slowest mini bike in the Cars and Cameras inventory, congratulations!
I think that it would be such fun, just really a blast working around the three of you, it would be just fantastic.
I can't wait for the next video!
Kool build 😎 hopefully the wheels can be saved 👌 the nostalgic look would be awesome
I had a 1978 Honda 250 Odyssey 2 - stroke a few years back and one day I started it and it back fired and started in reverse
Really love that c&c bird front plate you guys made - kinda wish that was more prominently acknowledged in the video because that's dope af
I don't know exactly how to describe it but that bike is the best thing ever. Need those old wheels though.
Ike! You are correct!
Reverse on snowmobiles when activated changes ignition timing to run the engine backwards! It's very common on 2 cycles that need a simple reverse feature.
In theroy yes a 2stroke will run in reverse for example in some snowmobile engines to put it in reverse you hit a button which makes it run in reverse which in turn makes the snowmobile go in reverse but the magneto in some engines are directional and only work when the magnets pass by it in its intended operational direction.
The ingenuity y'all have with these projects is why I look forward to each next video you release. Thanks for the entertainment team!
I have 2 of these Jacobson engines they are very dependable and have plenty of power.
Hey guys if I'm not mistaken Tecumseh made those motors for Jacobson. They are not a high rpm motor, as I remember 4200 was max rpm. It was great to hear that little beast run.
Now back in the day it was this motor or it's bigger brother that were the competition for the Macs on the racing carts back in the 50s and 60s. I know this because my grade school friend raced gocarts in the mid 60s.
Love seeing you guys get into some vintage engines and bike builds! the engine is probably the same age as the bike. Jacobsen was originaly a mower company and had big crude two-stroke uprights up until they bought the pattern rights to the johnston utilimotor in the 20s. made by the same johnson that makes boat motors. that johnson utilimotor engine evolved into the engine you have after years of renditions. it would have been on probably a mower called a 4 acre since it has the big tank. not a go-kart motor or bike motor originally. they should make good power though if tuned right. the muffler is a stove pipe style muffler that would work best for power if the extra pipes are removed and more holes in the outer pipe there is a lot of restriction in them loosing power for quiet mowing. To save your old ignition coil id suggest not pulling the wire to kill an older motor as it can make the coil short internally. they also tend to have pinging noises do to how thin the cylinder is and most don't have needle-bearing wrist pins. the timing of the mag is timed earlier to help with better power. I've worked on all three engines from the early one, johnson, and the later ones. fun motors. if you have any questions or possible need any parts for one I do have some. i also have a lot of other odd engines on my channel if you want to look. love seeing the older builds keep it up!
That thing is sick looking even if its slow. Love any sort of minibike content.
It looks really good guys. 👍
Charles has the Forest wave down pat.
I have used my wife's cricut cutter to make gaskets. Reassemble the torn gasket with tape the best you can, use a flatbed scanner and scan the gasket. Convert the scan to an SVG with Inkscape and then get the cricut to cut a new gasket out of gasket paper.
Back in the early 1970’s I owned several Yamaha 360 enduros. Many times when kick starting them hit would kick back (dangerous for legs ankles and feet) but it would start. More then a few times I would give it some gas and let the clutch out to be shocked it was running backwards. Another fun fact there were some Kawasaki 2 strokes that had the carb under a side cover Down in-line with the crank. The first time I saw one I thought it didn’t have a carb. Those were the days!! Lol
I used to ride with a guy that had trouble with his 2 stroke. When kick starting, usually, it would backfire and spin backwards. He was the only one there that had 6 gears in reverse! Lol. Thank for sending me back to a better time. :)
The chrome wheels make it look like a cafe scrambler bike. Good job guys!
LOL on ringin' that bell!
Congrats on 1 million! You guys deserve it. I look forward to watching your continuing success.
Definitely the bird would be awesome when it’s done
See if you could mount up a proper expansion pipe and silencer on there and that motor would run a whole lot better and make more power some new reeds and possibly a mikuni would help a whole lot too
Haven't even watched yet, and i am thrilled to see what your working on. This is cool stuff imo. Different, but not sideways or backwards lol.. yet...
Love the addition of Charles, and appreciate everything y'all do! Before a month ago I had zero working knowledge of small engines, now I have my own custom mini-bike largely thanks to the awesome content y'all put out! Keep it up!
The shot of the rotating assembly is considered as the primary compression chamber. There are transfer ports from the there (rotating assembly) to the secondary compression chamber (top of the piston).
The exhaust should have fiberglass mesh.
Certain snowmobile two strokes did run in reverse. The ignition timing and fueling was a bit different than this.
Love the show !!! Dont ever stop
Hahaha the banter between you two 🤣
My dad had a 2 and 1/4 horse 2-stroke Jacobson lawn edger. I'm 58 years old and it was old when I was young it ran great the muffler was the engine running against the concrete it had a little rumble a very unique sound there was no muffler it just reverberated off the ground!
In the fifties and sixties you had Jacobson and Lawn Boy two stroke mowers. Jacobson also made 4stroke mowers. Thanks.
looking good!
2 things to suggest: 1- maybe try fiberglass to fix the holes in the rim??
2- to align the sprockets, clamp a straight edge on the 2 sprockets and boom! aligned
My EZ-go golf cart had 250cc Robinson two stroke. To go reverse it started the engine Going the opposite direction.
Chances are, timing in one direction will be set slightly advanced; maybe 3 or 4 degrees. Running it backwards will definitely cause the spark to fire after TDC, 3 or 4 degrees. Some older two stroke diesels are set at TDC to run both CW and CCW. But your Jacobsen seems to be a lot newer, even being old, and probably won’t run both directions.
You guys are mad scientist of small engine. When I thought you couldn’t possibly come up with something new. Boom another crazy cool build on its way
That bike is Old Skool Cool! I'm a big fan of 2stroke and if you can get it up into the power
band I think you might find it could exceed a 6-8hp 4stroke.
At 14:20 removing float bowl de-laminates its seal. It's nigh impossible to re-seal, replace is best to stop inevitable leakage. Run in reverse only with timing change. Bravo for the rescue!
It's a spark thing. You could tweak it to make it work. Part of it is timing.
Being a old guy who used to play with those engines when they were newer. They are a bit noisy. Even the old dirt bikes. They also had a Clinton engine just like that one. 2.5 horsepower
There is a 2 stroke built by Villiers that runs in forward or reverse. I dont know the details but it was used in Pengor Penguin and Beaver amphibious atv`s. Reversing electric start determined which way the engine ran as this was the way these atv`s had reverse. Yup you shut off the engine, turned the key in the opposite direction of forward start and it reversed the current to the starter and cranked the engine backwards thus allowing a reverse "gear"..
After my countless number of hours spent on TH-cam, I’m surprised I’m just finding out about you guys now..
and am I ever glad I have! You guys are so likeable. No wonder your at a million subs already!
The three of you work together really well! Have you considered taking a rim and using your metal bender to make a steel hoop 'tire' for it? You could do one of your old experiment videos with leaving it plain vs knobs vs steel tread vs rubber tread vs bolts tacked on vs full Amish tractor steel blades, etc. Definitely would need to have front and rear suspension, as well as really good fenders though.
