What size main jet works best below 3000 ft? Mine had a 153.8 stock, I put the 155 in that came with the dyno-jet kit. Seems too rich now, no power! Might try the 150. Anyone have advice? Thanks

Why you changing the jet? Have you done other modifications? Have you done plug check?

Trying for more power! Only other mod is tip on muffler.
