Carb recommendation 440

You don't need a new carb. You need a better tune up. I'd use Thumpr Carbs. If you PM me I'll give you his phone number. Call him with the carb number and he will get you straightened out.

That carb is fine (as long as it is NOT a 3 circuit).
sounds like performer RPM and 850 quickfuel territory to me . 1050 dominator is not needed on a warmed over 440. the team G is a terrible intake for runner scatter too, I have been playing w/ one all winter there is hope for them, but a he-- of a lot of work.
