ONE of the most common things to happen in this scenario (and over looked) is does it have a top mount starter and has it just been replaced? Often times on Fords we've found that someone has installed a standard rotating starter on a reverse rotating application (parts stores don't know the difference ,its easy to do) ,so there wil be spark ,fuel and compression but no start if this is not the case :Pull the spark plugs (set aside to clean and dry) spin the motor a while to clear fuel (coil disabled) ,articulate TDC @ the dampner and check the rotor position, recheck your firing order and firing order rotation, Drain some fuel from you carb ,put it in a clear dish and see if its h20 contaminated ? IF everything check out put the plugs back in advance the timing a few (clicks)degrees past (before TDC) and whack it with a shot of ether If it doesn't try to light STOP and call me I'm happy to help Tom
