Thanks for the info. I was observing what you guys are saying about the tempurature flutuations on the cylinder. It just seemed that when a guy at the club flew for about 7-10 mins and the thing showed 30 degrees cooler I got worried. Now I think that the dirt I found in the carb is to blame because of how bad it started running. I am going to get a new plug, retune and if it is still running bad I will rebuild the carb. I did take the gasket out to access the little fuel screen and it seemed nice and soft. I will follow the manual and see what happens, although I feel better about the temp of the engine. Thanks again.
