It's beginning to sound like I should order a few sizes of each type of
jet (PAJ2, PFJ, MFJ) and have them on hand while I'm tweaking. Will do.
Question: Are the numbers of the jets a direct correlation of the size?
i.e.,
Does a Mikuni 160 main jet have a .160" opening? If so, why wouldn't a
DJ 160 be the same as a Mikuni 160? I understand that they're not.
