    Just recently purchase a 1940 Ford Deluxe at auction that sat in a barn for 30 or so years. I've replace the tank and fuel line and rebuild the fuel pump. Had the radiator cleaned and serviced along with new hoses and installed thermostats which non where install on the car when I replace the hoses. The few time I've drove it would stall when I'd slow down to make a turn and after driving for 4 or 5 mile it will not restart unless I let it set and cool down. The engine doesn't over heat, I've started it and just let it idle in the garage but after 30 to 40 minutes it will stop running and it will not restart until it cools down. It starts like a charm every time and the engine isn't overheating wants the problem? Regards

    Do you have a vented gas cap?

    Check the fuel pump, sometimes the glass fuel bowl mounting flange gets warped from over tightening the wire bail that's holds the glass bowl

    later kb
     

  5. When I does not fire up after running/stalling, do you have spark to the plugs? Gas to the carb? Air/fuel, spark......those are required to make it run. Fundamental diagnoses are needed before we can be of use to you.

    Is the heat from the engine after it gets warmed up causing a issue with the coil?

    I had issues with ot car that had a bad coil and after running for a half an hour or so in any outside temp it would do the same thing. The coil would warm then short inside.

    Your the third person to point to the coil. Thanks

    I really don't believe this. The gas cap is a target of much use and usually they are replaced a couple times on cars. Maybe yours got replaced by one without a vent.

    You said you replaced the tank. Most new tanks aren't exactly like original. Did the new tank have a separate vent?

    If it's not the coil, it might be your starting procedure. A good friend that was thoroughly experienced with flatheads told me to absolutely NOT touch the gas pedal when restarting a flathead that had just been driven and was warm. I thought he was crazy but I practiced what he preached and dang if the old Ford flatheads didn't usually start right up!
    Just sharing what has been shared with me. For me, the culprit on issues with newly acquired vehicles with flatheads was usually the coil. YRMV

    The tank was purchased for Midwest Early Ford I believe it was a Drake tank. I'll look into that, thanks for your feed back.

  17. I've had much the same issues with other points ignitions. Turns out noting more than a, going bad condenser. If so, the run cycle will get shorter and shorter eventually taking out the Points.

    Are you saying just replace the condenser?

    Thanks and thanks for the laugh
     
  22. You can't figure out your own problem, but you doubt I've had a much the same issue come to me, and a condenser alone cured it? Why would I waste my time or yours if I hadn't in fact done this?

    Wizzard is on point (so to speak). Replace the condenser with a good one (don't skimp, a lot of them are crap anymore). I had this issue with my 62 Nova a couple years ago and it was cured with a ten dollar bill and a trip to NAPA. Most guys with points keep an extra set and a spare condenser in the glove box.

    All this speculation and we still don’t know if he checked it for spark or fuel delivery when it won’t start?? Waste of time for anyone to diagnose until we know

    I had the same problem for a bunch of years. After checking everything over time I treated the ole flathead to some new Autolite spark plugs. Problem solved. I had even gone to Pertronix dizzy conversion. I did not know the age of the old plugs and should have replaced way sooner.

    I replaced the coil and condenser with new one from Midwest Early Ford. It started right up ran at idle for 1 hour shut it off and restarted it right away and ran for another 30 minutes with no shut down. Still cold up here so I didn't get it out on the road but I think that has solved my problems. Thanks for all the help HAMB!!!
