Hallo I am about too run a singel carb (riva power bomb). Have checkt the data base for jetting, but cant fin someting that will match my setup ( ADA girdel head 185 psi, FP type 4 MSD enhancer,RAD flywheel,COLD FUSION couplers, HOOKER 9/15, engine 61x/62t stock port). Does someone have a good starting point for jetting ?

Not sure with a dry pipe but I would start with 140 pilot and 160 main with about 2.0 n/s at around 20 POP OFF. you may need more with a dry pipe though. Good place to start is all I can offer. The Type 4 is a dry pipe right????

Shouldnt he also use a #65 main jet as a restrictor in the return also, then he also should be able to run smaller jetting than that?

what octane gas are you running? With the type its recommended to use 37cc dome on pump gas. I used to have a very similar setup but with dual 38s and ripped very hard (still does)

With a dry pipe, I would start out really rich and jet down. I would also stay away from running WOT. That pipe will lean you out.

Actually you should put a 30 jet in there to start 60 would be used for dual carb restrictions
