1100 RPM is right about where the carb starts to switch from the idle circuit to the power circuit. Sounds like a carb problem. Do you have to feed fuel with the primer at 2000 RPM or does it run by itself? One other thing to check is cam timing, which could affect the airflow through the carb, although probably not. __________________________________________________________________________ ______ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] ___________________________________________________________ T O P I C A The Email You Want. http://www.topica.com/t/16 Newsletters, Tips and Discussions on Your Favorite Topics
