Well, none of the rebuild kits fit 100%, and the needle valve seats don't remove (pressed in), and they come with one of two different sizes of choke threads.
I never get a wide open throttle. It starts sputtering.
Right now it needs full choke to run. This carb was fine until it got junk in it, despite a good paper filter. I dissembled it and cleaned it, (Ultrasonic cleaner and air).
I had about 50 paper filters I bought in bulk that came apart in the ethanol fuel. It's not one of those.
