I made a ryobi good engine.
I made a poulan 46 great engine

Now I want to make a 60-70cc engine to power a 1/3 stoudacher that will weigh about 20lbs and I want good 3d power and I think a engine this size would be great.

What are you using for a converted engine around this size and how much does it weigh.Do you have any pictures?

ps

I want to do a conversion, I like to tinker, please no coments about, just go buy a zdz or bme etc.
