hi all, can anyone let me know if this sounds correct? puch maxi 2hp, biturbo exhaust, removed a couple of screens from air box, had a jet size of 58 in carb when i bought it. it was four stroking at full throttle... went lower to a 56 jet size, corrected!!! no more four stroking..... spark plug chop shows more on the richer side, not gray,but not soak and wet either. has under 1000 original miles. ( guarenteed) did i do the right thing by going lower in jet size, and did i lose any any proformance by going lower?? thanks for any info you guys and gays may have. :)
