I know 1320 is a 1/4 mle. I was saying that "98.7 1320" has the red, then green with no warning on when it is turning green! I dont like that.

Air bleeds is what controls the air fuel mix at high rpm's, they are on the top of the carb near the venturies. The jets control the air fuel mix for low to mid rpm's. The air bleeds are what ristricts the air from coming through the emulsion tubes. The smaller the air bleed the richer the mix and the bigger will lean out the top end. Oppisite of the jets.
