Grey88gt, Thanks for the reply, your post didn’t make sense at first about agreeing with rev, so I read his post over, I thought he was talking about the pcv valve when i replied, I now see it’s the power valve. Like i said earlier, i changed mine to the single 6.5, maybe i should put back the two stage, which is 11.5 - 6.5. The primary jets are 622, and the secondary has a metering block with out jets. The carb i have is the 4180.
