I can't answer your question, but though the original poster is gone, this is a good thread to bump up every now and then.

i ilke the idea of changing the accel pump nozzles to get better accel, i think i will try that first, my main issue is when i accel the carb is throwing so much fuel that i get black smoke coming out of my exhaust and my plugs foul out, the acceleration is ok, its not hesitant or anything but, i know it can be better, after i changed my jets from 73's to 68's that helped alot, i tried changing the accel pump diaphram from 50cc to 30 and it works but it doesnt, it has a flat spot if i mash it
