Main jet tuning... ...in France

PV has ZERO to do with cruise and A/F ratios.

The way holley suggest choosing a PV is so wrong it's not even funny. That method only gets you something that MAY work. You have an A/F gauge, use that to choose a PV, not some formula that has been proven wrong way too many times. Same as the carb sizing formula... RUBBISH.

Ok... And what's the process I should follow using the AFR gauge to find the good PV?
