Power Valve Selection: The Definitive Answer

You said it lightly surged at cruise iirr.
That's the jet. 4 jet sizes at a time? Be nice to see one change at a time, like 2 jets @57 Awesome to hear it's gone, just keep an eye on the plugs though... that's a really big step in enrichment...and IF correct, means the carb is a hair too small. That would be suprising to me.

Well, like I said in the PM, that was the quickest I could get a bigger jet. They couldn't even tell me when or IF they could get something smaller. THose were in the DC in Atlanta so I got them. It still BARELY and I mean BARELY does it, so I think it's about right.

Also, think if this. I KNOW it clearing that up was not the PV, because my cruise vacuum was 12hg and the PV is a 9.5 so it's not even opening then, so it had to be the jets that cleared it up. It seems to be running better, but like I said, I have the 3.5PV coming as well and I plan on putting that in just to see what the difference will be. I've never really played around with one this much, so I am learning as I go. I think it might can stand a smaller pump shot too. It has a 25 in it and I have a 21 coming just to "see" what effect that has. I can always back up if I see something negative.
