I have a NOS catalog, and they list nos jet's and hp levels, but all the fuel jet recommendations are for 5-7 psi for carburators. These are flywheel hp jetting. Their nos jetting for a 100 shot is.047, for a 125 is .055, and 150 shot is .063, and 175 shot is .073. I would start with your fuel jetting about 10-12 sizes smaller for your fuel jets, and lean it out small steps at a time, maybe two steps at a time, until your a/f ratio is around 11.5:1. I would recommend a wide band, and probably some dyno time.
