RE: OS 95AX
I just bought one tonight and I intend on breaking it in tomorrow. I will post numbers as soon as I have them. It's one dang good looking engine and several guys have them at our field. Everyone of them run flawless and that's what led me to buy one. Hope mine's a good un.

RE: OS 95AX
OK, broke the beast in last night on Wildcat 10%, MAS wood scimitar 14X6, stock powerbox muffler and OS #8 plug that came with the engine. Temp was 63 degs., humidity 73%, altitude 95'. First 12oz were ran very rich and no rpm's were measured. Second tank, 300 rpm's down from peak was a very comfortable and steady 10,100. She was only at peak for maybe 3 to 4 seconds but seemed to be very happy there with no indications of wanting to sag. I am impressed by this engine. It's my first new OS in over 10 yrs and all I can say is WOW. I quit buying them because of the price and then stayed away because of the liner peeling issues. I have been witness to the peeling issue and was glad to see they had the 95AX available in a ring version. This engine is as smooth as silk and transition is as good you can get. I am going to try some more props later but for now I want to get it on the plane and start enjoying this work of art albeit expensive work of art.
