I did a mistake calculating out the crank pulley size....another is in progress now..,the reason for the really low psi. I´m using a GM Hei ignition, and with the full recommended setup it delivers some minor knock..Hei´s are known for the higher than normal BTDC/adjustment, but fixed by a adjustment, and connection of retard.
Sparkplugs are dark brown, but even! My flow direction "flaps" seems to be functional on the distribution!
Main "trouble" is the rich mixture at idle with the 500 holley, who i dont seem to get fixed. Its straight ok at cruise, and superb at full power.Lowered the float as much i can without making stumble,seems to changin of the idle restriction channels is needed...somebody done it? Suppose it is to plug them and drill with smaller taper than original.
