40 or 42 pilot and a 152 or a 155 main. Do you have a pipe on?

Jet higher, most owners numbers are too low. Get you a bigger carb, set main jet higher.

I'm good with jetting questions so you should'nt have problems if you ask me. He did'nt say weather he has a pipe on or not if he does then the numbers will be higher.

I suggest 40K Pilot. 150K or 152K Main Jet if you're below 3,000 feet. Put a new plug in and Plug check it when you're done. The plug porcelin (just below the electrode) should be a "paper bag" brown or tan if it's jetting proplerly. Good Luck!

No was'nt sleeping I did'nt know that he responed to the post, my email has'nt been working which is why the delay, to answer your response put in a 152 main I think you could almost get away with using the stock pilot but if it's cold put in a 40, most people put in a 42 but sense you have stock exhaust a 42 pilot would be to Rich.
