It could also be a tad rich. You are supposed to break in the engine at a rich setting but you have to tune it for better performance after. Did you lean the engine out any, what have you done to tune it, and what kind of temps are you getting? The more information you give helps us help you.

What is very hot? If it is very hot (280+) you need to go rich. You want a steady flow of smoke when you are running.
