You are correct sir. The larger the number the richer you run. What are you running with a 170 size jet?

more main jet equals more fuel? so if your lean at 165 go to a 170 for more fuel? :bang:[/b]
Yes but not all the way from idle on up...it depends where you are lean. From idle up to somehwere around 1/8 throttle the pilot circuit controls the amount of fuel to the engine. Once you hit the lower midrange then the starting point of the needle is plays a huge role and then by the time you hit the upper midrange the profile of the needle taper becomes significant. It is not till you get to the high speed range that the main jet becomes the biggest factor in determining how much fuel the engine gets.
