Love the tutorial! I built it from another one though. I got mine to a 6000rpm redline. Here's how: first, you want to put tape everywhere that air could possibly leak. So cover the whole outside of the cylinder with duct tape. Leave the hole open on top but put tape around the edges of the hole. Take a Dremel and sand down the edge of the piston and make sure it is facing AWAY from the front, or the spot you attach the vacuum. Next, shave off all the all the material you can get away with, piston and valve. After that, light flywheel. Use the lightest you can get away with. Avoid using a flywheel with a tire on it. Lastly, superglue and lubrication, make sure everything is secure and then smother every moving part that is capable of friction with a lubricant. I use wd40. BTW I'm using a central vac so it might make more suction. Also don't forget to put a tire on the spot of the vacuum your attaching to the engine for a better seal. Best of luck! Hope you found this helpful!

Yes that does drastically increase performance but I like to make engines that any one can build.

imma rebuild it a couple times to make sure I'm getting it right, I'm also using a 4.5 horse power shop vac so could there be to much sucking,? making the valve to hard to push up, I never thought id say to much sucking power but I've never made a engine like this

the one cylinders are hard to start if you don't have the right flywheel for how much vacuum your using.

Hello, the engine doesn't work, it stays up but never comes back. Is there any solution?

mine only works with a heavy flywheel and barley runs, I built it to your specs except the brown axle on the crankshaft, do you have any idea what the problem is ? its been driving me crazy lol, if so plz respond😭

So you actually need that brown axle *the tan one* it helps with friction and you can’t have alot of friction on the crankshaft of a engine or the piston

thanks for the turorial! quick question though. I dont get how you rev it up, if i put my finger over the valve, the engine will slow down or stall. Do you know why this could be? Thanks

you have to use a light touch and let your finger float on the valve.

Can you explain what the valve actually does because it just looks like an upside down butterfly. Btw the out of focus video is really annoying could you just use your phone or something cause it has auto focus
