The F1 is adjustable from 75-150 and the F2 is adjustable from 150-300. They are only ~$15 different in price. Is the only difference between them the jets or do the F2 solenoids flow more. Right now I only want about a 100 shot but if for 15 dollars I could get better solenoids then I could still jet it for 100 right? Which solenoids would last longer?
thanks
Dustin
