Mike:
One other thing - you mentioned you are using a Perry Pump - this engine usually comes with it's own pump in the backplate of the engine. If you have this pump on the engine, and then use the Perry on top of it, you may be flooding the engine. Also, ny experience has been that you must run the idle and lower settings pretty lean to get it to run right, and there are no standard settings, I have this engine in 3 of my planes, and have worked with a number of others in friends and everyone seems different. In fact, if I change an engine in a plane, I keep the original carburator. This keeps all the settings the same.
