Oh and I'm talking about the main jet not the idle jetLike Kart43 suggested, I'd start with a .039 - .040" on gas.
That's assuming no other mods (besides the pipe and air filter) have been done.

Yall?I have a pod filter and header on my 390, with a stock carb. I jetted it to 1/16 but its super rich. What size do yall recommend jetting the carb to?
