HI,

Thanks for the pics!

Hmm... My little 16cc Kioritz had ball bearings, and all the others, (23.6cc and up), I've had have had ball bearings as well. I do have a 21cc engine that I haven't taken apart yet. I was going to use it to convert for a plane for my brother. Maybe I'll just leave/use it as a blower.

Good luck with your project and thanks again,
