carburator

[johnfrenchsr]

I have had my carb rebuilt.It came with 137. I have taken them off and put 150 what was in it before do in need to put the old needle jets backor use the new ones. It is running to rich do I need to go one leaner or two on the needle jet.

Unless you have modified the intake and exhaust, I would go back to the 137's. 150 is way to rich. I have after market pipes and a Uni foam air fiter and I run 140 main jets in my 1179 big bore.
