1983 Ford F-150 Hard starting

I recent could not start the truck it will crank and turn the motor over an after it turning over sometimes 6 or 7 times it will hit so I replaced the plugs checked my distributor cleaned it up and it started fine then it wouldn't start again the only way it will start is if I hold the pedal to the flirt hit the key and if I get lucky it will hit and speed up the motor and sometimes hit again if it does this it will start enought that I can give it gas till it lines out driving it seems fine but doesn't really have a lot of power and takes a while to get it wound up could it be my coil I checked it's getting gas the float is ok all of that just doesn't wanna start
