Sorry for hi-jacking this thread,but I'm going thru a similar problem with my six bbl setup.
I have 9" vacuum and after reading this thread thought maybe I would change power valve because car don't want to idle,it also will water your eyes.The idle seems to flux around after being fully warmed up-either goes from 650rpm to 1300 rpm.So I changed to a 4.5 PV last nite (1/2 vacuum).Idle seems much improved now.still waters eyes.If I cover center carb for a sec.with hand and let go ,it will rise high in rpm.Is that normal?sprayed carb cleaner all around,can't find a leak.Jets are 70's in center.Should I jet down by 2?Should I buy new valley pan?
