"im also assuming that since you know where the rich conditions are occuring, that you are using an in-car A/F monitor of some sort."

Yep, I'm watching the people I pass to see if their eyes water or not... It's a Cyberdyne gauge, I was not sure it was working until the A/F ratio rose at WOT. Until then the whole darn gauge was lit. I decided it was time to actually start to tune this thing. Hey, maybe I'll even adjust the timing at a test and tune...

I had to look this up, even though i was just reading about it...
PVCR- power valve channel restriction
IFR-idle feed restriction

The Holley book I have does not get into the type of tuning you guys are suggesting, and I correctly thought i needed. A decription or better yet, a picture of what bleeds are what, and where the PVCR and IFR are located would be cool...
