Uncorked, vented airbox (SRC perforated number plate) with a full Big Gun pipe.
68s pilot
178 main
B53e needle with clip on the 2nd notch
Primary riding area 30 ft - 4,000 ft.

Thanks!
the circuit that resides between the pilot and main is going to be the jet needle. i would try to drop the clip on the needle to the 3rd notch from the top. if it is still poppy and has the hesitation, try the 4th notch from the top. that is all i have for you.
