RE: Fuji 32
 

Did you mix the Amsoil at 100:1 or 80:1?

RE: Fuji 32
 

My PK props routinely turn less rpm than the others, but may pull as well or better...The size of the carb should have no effect on rpm, as most are bigger than they need to be anyway...Except for the dinky carbs on some of the weedeaters...:D
