O.S. .20FP on Flite Streak.

I won this in a raffle a few years ago. I could not get it to behave and fly properly. i didn't expect much as I have bad luck with ARF planes in general. I read up on the proper set up for the plane and the engine and it flew a lot better but the engine wouldn't slow down. I measured the venturi and found it to be for a .46 size engine which would make this smaller engine go crazy. I had a proper size venturi for it and installled it. There was a big change in the needle setting and the engine ran much better.Same prop and fuel. I didn't get a chance ot flight test it today maybe tomorrow.
