WHAT is the deal with carb jet sizing? An 85 or a 92 is WHAT in terms of a drill bit size?? A numbered drill bit size (1 to XX)? Letter drill bit size (A to Z)? Fractional drill bit size, now theres one I understand!
I want to drill some jets for experimental use on a small motor. I found a set of 'jet drill bits' for about $250 that are numbered in 'jet size', whatever the heck THAT is! $250 to drill a couple of holes is just to much! Gotta be a cheaper way.
Are some jets actually 'tapered' to increase velocity effect? If so, then drilling a stright hole might not be a good idea.
Anybody got any input on this confusing topic?
