Fcr39 jetting question

Recommended Posts

Hi everybody,

I always read about changing the main and pilot fuel jets to make the mixture richer/leaner but i never read anything about changing the main and pilot air jets (apart from when removing the coast enricher) aswell to let more total mixture in. Is there a reason why noone seems to play with the air jets, is it just super complicated or are the stock ones already the best solution for power? Would it not work to have the largest air jet possible then choose a corresponding pilot jet to get the right richness?
