I want to test an HP 950 in place of the HP 750. My 750 is using 83/85 jets. What should I start with on this 950? Same? up size 2?
Run it with the stock jets. Almost every Holley carb I've ever used works pretty good with stock jets. The factory engineers know what they are doing when it comes to main circuit calibration.
Agreed, but too bad they aren't assembled by engineers and have seen em whacked out and wound not run for chit as they arrived. Good point Brad about the venturis(my bad)although the two 950'2 both small and larger venturis were close in jetting.........If you don't map out the WHOLE carb, it's guess work period.............
