b717doc, didn't I answer this with a couple of posts in another thread? Did you not see those or did they not post?

Anyway, what I had said was that if you are happy with the performance of your 32cc on a 17 lb. plane, you might be ok with a Homey 25cc, though I think your plane is a touch heavy for that size motor. It all depends on what you want.

I think that if you would have your flywheel professionally balanced, you would like your Mac 32 a lot better. Why not give it a try? It's a lot simpler than doing a new motor!

Take care and good luck,
