Re: need help finding out make of engine
Yep, those are pictures of a basic Chinese two-stroke bicycle motor. I couldn't guess how many CC just from a picture. But I know that on the That'sDax web site, and probably a few others, there is a photographic tutorial on how to mount these on a bike. Pretty easy step by step instructions there. And you'll find out what extra parts you'll need if you happen to be missing some hardware there.
It's not hard to find instructions for mounting these, I imagine. Once it's mounted to a bike, then you'll be able to try starting it and learn how well (or if) it presently runs. From there, I'm pretty sure we can help you get it running nicely.
