Some of the Black Floats were not sealed up very well by Holley or Modifiers.

Very Few understand Transfer Slot position and the effects it has on the ability of the carb to perform properly.
That is why you get the Primary Side "Blade Position Window" vs the Transfer Slot perfect and add extra idle air if needed with secondary blade opening or Idle By-pass Air circuits. Tom V.

That's interesting, regarding using a PV that is 2 or 3 inches less than car idling or in gear. I always thought one divides in half was bang on as holley's videos mention that. I certainly went down the path of larger squirters and 50 cc pump arm to overcome lean stumble.

11" divided by 2 = 5.5 then add one inch of vacuum so the correct number to be installed would be 5.5 plus 1 = a 6.5 Power Valve. A larger value number will ADD extra fuel SOONER. Tom V.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
