i belive its flooding it self out. this can be caused by the gas boiling out of the carb and flooding the cylinders. you can usually hear this. sounds like the carb is boiling if you put your head next to it right after you turn off the motor. if the choke is coming back on too quickly this can cause it to flood also. is the choke plate closed or open on the top of the carb right after you shut it off or after 5 min of siting it needs some adjusment or has someting wrong. the coil could be weak and when its hot its geting weaker. i would see what color spark it throws. take the distributor end of the coil wire off and give it about 1/4" gap to a ground. then crank it. you want to see a white or orange spark. if its blueish then its on the weak side. to check float level on a carter afb you need to take the top off of it. turn it upside down and measure the gap between the floats and the carb top. i dont rember the specs but im sure a google search will give them to you.
Sounds like the old days when people used to rev the motor when they shut it off. This would puddle fuel in the cylinders for a quick start.
its got a manual choke and its always open. the choke never closes. i tried getting close to it and i dont hear a boiling sound. however i do heAR a ticking sound when i turn it off. if the spar is blue should i change the whole distributor, just the distributor cap, or the wires only?
Too rich huh ? Then why did the spark plugs look like new after a two year run ? It was by no means too rich. The combo was basically an Explorer Shortblock and cam, topped with a Holley 570 SA carb with the out of the box jetting, sparked by a Crane XR-1 and a Mallory Promaster coil. The key ingredients here are the F4TE cam, which pulls a stronger vacuum at idle, which lets the idle circuit kick in instantly when you crank it. That and the hotter spark and advanced timing are what made it all work. All I did was crank it for maybe 30 secs before it fired off and idled on it's own....................exactly like an EFI system.
[quoteAll I did was crank it for maybe 30 secs before it fired off and idled on it's own....................exactly like an EFI system.][/quote] if your efi system takes 30 secs to start then youve got problems. efi should always start in under 5 sec.

Because it was 25*F outside and I wanted to see if it would start without giving it gas. It did, and it idled without touching the pedal, without a choke.
Try pumping it one time. If that helps then you know what to do in the future. Pumping it shoots a squirt of fuel into the intake which may help. I wouldn't pump it more than one time or you could easily go to a flooded condition. Trial is the way to find out. Pumping it also releases the choke to close or move to a position that would help with the start up. RS
