First post. I rebuilt the engine and am having a hard time getting it to run right - dang it.
Symptoms: Hesitates, backfires on initial acceleration no matter how I have it timed, and does not produce much torque.
Equipment: New everything in engine, new Pertronix Flamethrower dissy, new old style fuel pump, stock rebuilt SU's.
Data: Compression 135psi on all cyl, checked and recheck value clearance, vacuum measured off front carb just above nil at idle, approx 15in at rpm, centered jets and equal coordination observed during accel, equal vac at idle, mixture test ok, I know the timing marks on the crank and cam are correct.
What am I missing? Sheesh.
Oh...and thanks in advance.
