I have a 1977 mustang ii with a 289 Windsor v8 out of a 1968 mustang in it. The car does not want to go up in RPM's as I push my foot down on the pedal. It hesitates and stutters as I try to increase my RPM's as low as 2500. The car runs perfect while idling though. I think it has something to do with the fuel or air delivery.

WITH A FLASHLIGHT, WHILE LOOKING INTO THE CARBs THROAT WHILE IT'S NOT RUNNING

IF YOU ACTUATE THE THROTTLE LEVER

CAN YOU SEE 2 NICE AND PERTTY STREAMS OF FUEL SHOOT DOWN THE BARRELS (THEY SHOULD RESEMBLE SQUIRT GUN STREAMS ON A SMALLER SCALE)

ARE YOU GETTING 2 PERTTY, SQUIRT GUN LIKE STREAMS OF FUEL INTO BARRELS
WHEN THE ENGINE IS OFF AND YOU MANUALLY ACTUATE THE THROTTLE LEVER ON THE CARB? (USE A FLASHLIGHT! NOT A LIGHTER!)

HAVE YOU DONE THE TIMING?
