I have a 46 la that has been sitting in a box for about 3 months after a crash. I had cleaned the engine and put it up. I got it out and put it on a new plane and started the engine to check it. It fired up and ran fine. This was my best running engine, never had any problems. Anyway I took this plane out last night and started it up and off we went. The plane was in the air in no time. While tring to trim the plane, (it kept wanting to climb) the engine wanted to stall. I kept turning the plane back down but it did end up going up stalling on me and dead sticking. Once I got it back down I tried to restart it. It started but would not idle up to full rpms, I've never had any trouble out of this engine, I tried to adjust the needle but it just would not idle back up to full. Does anyone have any ideas? One more thing, Why would it want to climb like it did? the elevator was level. the plane was a little nose heavy but the book said a little nose heavy is good for a new flier.
