I did some research and found others seem to have no trouble putting a gas engine on this plane. However, it appears 25cc is on the low end of acceptable power level.

I did some reading and decided to upgrade the homie to 30 cc. I bought a new cylinder and piston. Hopefully it will run at 8K RPM. A little extra power does not hurt.

I am not keeping track of how much this is all costing - it is the learning experience and kick I get out of it that pays back for the obvious cost overrun :-)

I would have come out pretty close to even by buying a gas engine new but hey who's counting....

Thanks for all your help.
