STILL TRYING TO GET THIS MOTOR LINED OUT, NOW I'VE GOT HER STARTING GOOD IDLING GOOD TIMING SET TO WHAT I THOUGHT WAS CORRECT BUT WHEN UP I REV IT UP AND TAP INTO THE SECONDARYS ON CARB IT WANTS TO POP AND MISS AND SPIT FIRE . FIRST CARB 850DLB PU. HOLLEY, SECOND CARB BRAND NEW 750 MAN CHOKE ELDEBROC. BOTH CARBS SAME DEAL, AND IT IS ONLY WHEN I TAP INTO THE MANUAL SECONDARYS ON THESE CARBS,SO I ADVANCED THE DIS. TIMING WAY FARTHER THEN I REALLY THINK IT NEEDS TO GO DON'T WANT TO SMOKE NO PISTONS BUT WITH THE TIMING WAY ADVANCED LIKE THIS IT SEEMS TO ACT LIKE IT WANTS TO DO RIGHT . ANY ADVICE?
