One more thing. I currently have a 31 squirter and the blue cam for the accelerator pump circuit. 30cc pump. I know that 28 is regarded as the typical squirter to use. I am of the thinking that a higher number squirter will limit the amount of time the shot moves through the cycle, But I have even gotten decent results with a 21 squirter. It just seems to have a small initial void with that and the 25. I have found that backing out the adjusting screw to limit the amount of fuel the pump can deliver has made some strides. I have been careful to be sure there is still 15 thousandths extra travel on the lever. I have also run the white cam with similar results. Always in the number one position. There are conflicting reports on the accuracy of the Holley pump cam charts particularly of the blue cam. I have seen the blue cam charted in two totally opposite curves.
It just seems to me to be a heat related issue. The car is not running hot, though.
