1971 Other Ford Models Starting Warm Engine

i'm assuming that this still has the points style ignition system in it. i would go for the regular ignition checks first then look at carb to see if it is overflowing with fuel after you shut the car off. If it does that means that the float level is to high in the carb. With today's fuel if the float is made of plastic, the center of it could have been eaten out by the alcohol in the fuel causing the fuel level to go high all the time. If that is the case you'll need to overhaul the carb and put a metal float or a new one that is impervious to the alcohol.

Thanks for the feedback! Yes this engine still has points. The carb was rebuilt 5 years ago. Would the float be a constant problem, or could it happen sometimes and not other times?

Thanks again for your reply!

With the float being down you would notice it more hot than cold. When it is cold the choke plate is partially closed and you don't get as much air in the carb. But when warm, you get what is called a hot soak condition and with the alcohol it aggravates the problem. If it's bad you'll need a new float. But test it first. It could just be dirt in the needle and seat. there is a way I used to fix them without disassembling the carb but it gets involved. Make sure you check the breaker plate as that used to wear out and effect the point operation. That would be easy to diagnose as the plate would move sideways and once it was removed you woud see wher eit is wonr.
