I HAVE A 66 427/390 WITH REBUILT ENGINE. CAR STARTS GREAT WHEN COLD. I HAVE TO CRANK FOR SEVERAL SECONDS AND PUMP THE GAS SLIGHTLY AFTER THE ENGINE WARMS. HAS A NEW HOLLY CORRECT # 3370 CARB AND THE FLOAT LEVEL WAS SET AND CORRECT. IGNITION IS A NEW TI WITH THE SOLID STATE AMP AND NEW HARNESS. AFTER IT DOES START I GET A PUFF OF BLACK SMOKE.I AM GETTING 8 VOLTS FROM THE "R" TERMINAL AT THE STARTER SOLENOID WHILE CRANKING , 3 1/2 VOLTS AT POSITIVE COIL WITH 4 1/2 VOLTS WHILE CRANKING. AFTER THE ENGINE WARMS I CAN TURN IT OFF AND HIT THE STARTER AGAIN AND IT STARTS IMMEDIATELY WITHOUT CRANKING. ONLY AFTER IT SETS AWHILE THAT I HAVE THE PROBLEM. ANY SUGGESTIONS WOULD BE APPRECIATED AS I DON'T KNOW WHAT TO CHECK NEXT. I THOUGHT PERHAPS A LEAKING CARB INLET VALVE SEAT BUT I DON'T BELIEVE IT WOULD START IMMEDIATELY WHEN COLD IF THE FUEL WAS LOW IN THE BOWL.

Re: STARTING PROBLEM ON 427/390
I HAD A HOLLY REBUILD KIT- THE REAR METERING BLOCK PLATE WAS SLIGHTLY BENT.I STRAIGHTENED IT AND PUT ON ALL NEW GASKETS AND NEW INLET VALVES AND IT TOOK CARE OF THE PROBLEM.
THANKS FOR THE ADVICE!Comment
