45 pilot in, fuel screw 2 turns out, 4th clip down on needle, 165 main jet, I still get backfires, (flames) and popping. How far out would be considered "maxed" on the fuel screw before I need to get a larger pilot?
Thanks

Ok, 170 main 45 pilot, 4th clip down on needle.. I think I stoped the popping, but now when I rev it a get a little white greyysmoke.. which means im running slightly rich. lol So i will probably close the fuel screw a turn and see how that works. If that doesnt, Ill raise the clip one notch on the carb.
Is it bad to run the engine rich for a little, I rather go out in the trails to tune it , its too loud around here. heheh
Atleast I accomplished SOMETHING though,, I thought I was out of hope for a minute there.
