05 RAPTOR 350 when you let off the gas going down hill it starts poping stay on the gas a lil its fine its not hurting anything just annoying so in this case would i turn the mixture screw in out out a lil? any help would be great thanks in advance --Jeremy

 

Popping on decel is the idle circuit too lean. If the intake and exhaust dont have any leaks, then try about 1/8 turn at a time, out (richer) on the mixture screw. This only effects the mixture in the idle circuit.
Once you get it set where you want it, slowly turn it in, counting the turns, until the screw lightly seats. If its more than 4 turns, youll need to go up one on the pilot jet, if its less than 4 turns, then set it back to that point, and youre done.
