My 4 stroke engine "Neptun"

[kosmos]

Hello,

here is a video from my 4 stroke watercooled engine. I named it "Neptun". The bore is 25mm and the stroke is 30mm. I designed this engine by myself, made the drawings and castings and machined it.



Best regards,

Sepp

Good job...
I think it would be better if your engine turned more slowly, try to mount a bigger flywheel

Hello,

the engine turned with 3000 rpm, but the carburator has no throttle at the moment. A bigger flywheel is also a good idea.

Hi you could make this simple carburetor when you open or close the needle you could change rpm motor's
