Hockey, Just that when I broke in my 82 Saito it only used three - four tanks of fuel in the 40 minutes. I just didn't know if you thought that maybe you had to have a gallon through it before you could fly it. The only thing with mine was that it needed some tuning to get it running right. One of the guys in our club is a whiz at that. He did some tweeking on the top end and on the low end, then do some more, then some more. Finally got it to where it had a nice smooth transition and stayed running on the low end. Last couple of 4 strokes I've gotten wouldn't stay running at idle. Rob
