Sounds like you guys are getting this engine dialed in. That is very reasonable for the ring and gasket, also tempting as i have not ran mine yet. Speaking of that, the plane it is going in is not going to get finished for this flyinig season so i am on the fence whether or not to even run the engine before next year. The only plane i might be able to squeeze it in to is a Great Planes 1/4 scale Patty Wagstaff Extra, it is probably too much engine for that plane. The other option is to modify the engine test stand to get some time on it. Any thoughts on that are appreciated.
