I have a 1980 Harley Davidson and when I put gas down the carb it runs good. I have had the carb rebuilt and still the same problem. I can't figure out where the adjust screws are at? The adjustment screw is on top with a t-handle and it doesn't make any difference on how I adjust it.

YOU MIGHT NEED A NEW THROTTLE CABLE..IF THEIRS NO MORE ADJUSTMENT IN IT..IF YOUR SET SCREWS AREN'T MAKING ANY DIFFERENCE THE POINTS ARE FLATTENED OUT AND NEED REPLACEMENT.WITH BIKE RUNNING AFTER TURNING THEM ALL THE WAY IN THE MOTOR SHOULD DIE IF NOT THERE NO GOOD..COME FROM OVER TIGHTENING..THEY SHOULD SEAT WITH LITTLE PRESSURE..GOOD LUCK..THE ADJUSTMENT SCREWS ARE IN BETWEEN THE MOTOR AND CARB AND BETWEEN THE AIR FILTER AND CARB..THIS IS USUALLY THE ONE USED FOR FINE TUNING..I KNOW HARLEY MECHANICS COST ALOT BUT THEY REALLY ARE WORTH THERE WEIGHT IN GOLD AS LONG AS THERE A SEASONED MECHANIC..ID TAKE IT IN FOR A TUNE UP WITCH WOULD INCLUDE CARB ADJUSTMENTS..BECAUSE WITHOUT THE PROPER KNOWLEDGE AND TOOLS ITS ONLY SO GOOD..BEST IS WITH A FLOW METER WITCH BALANCES THEM PRECISELY,,TO EPA STANDARDS..AND HARLEY S OF COURSE..KEEP THE RUBBER SIDE DOWN..
