If it's popping on decel (lean) than you need to turn out your fuel screw. If your fuel screw is out beyond 3 and a 1/2 turns than it 's time to go up to the next sized pilot jet.

Thanks, mine is 3 turns out.

Turn it out another 1/2 turn and see how that effects your idle and popping issue. If it persists than go to a 45 and set your screw to 1 to 1 and 1/2 out. That should work for you.

Is it possible to take the fuel screw out?
