Sure beats mine. I guess I'll run it a while and see if it breaks in and picks up. If not I'll pull it apart and see if something's unhappy. Shouldn't be, as I went through the whole engine when I set it up. My little unmodified Echo/Kioritz 23.6cc turns a slightly larger prop over 7500!! I wanted the Ryobi for this project however, as it is a Tiger Moth biplane and the Ryobi fits completely under the cowl with no ugly holes for mufflers, carbs, etc.

Wish me luck!
