Two Stroke Engine Moving Roughly

[Donkles]

I just put a two-stroke engine on my bike from a kit. I got on Amazon… I haven’t tried to start yet when I walk my bike the back tire moves in small amounts and it’s not smooth and when I pedal it’s very choppy… Should this move smoothly?

Please post some pictures of the engine drive and wheel drive. We need to see what you are dealing with. If you use your phone to take the pictures, you will need to down size the pictures before you will be able to attach them.

Kinda sounds like compression bumps which occurs once every rotation of the engine. You should have a clutch to disconnect the engine when it is not running and not straight drive.
