Malfunction
Two weeks ago took the 36 out for a 15 mile drive for a Car Show and Blessing of the Fleet in Darien, Ga. Got about half way and the engine just seemed to be running out of fuel. I use Marine gas only. Would not continue on its own power so called Triple A to the rescue. Got her back home, started her up a drove into the garage.
Today I started her up, ran her in the garage for about ten minutes, got up to temperature and shut her down. Half a tank of gas, new Drake fuel pump and a rebuilt 97. I’ve driven old flatheads for fifty plus years and haven’t had this happen. Dirt in the fuel, vapor lock, flexible line looks good, perhaps a computer chip malfunction in the burbalator, I don’t know. Opinions requested, John |

Re: Malfunction
Maybe electrical, condenser will do that, quits when it gets hot, runs when it cools down.

Re: Malfunction
Coil or condenser would be a place to look. Original coil or canister coil? A check of how hot the coil gets when the car stops running would give you an indication if it's the coil.

Re: Malfunction
If you are running a Mallory electronic ignition it might be the module.
I had the case where it would heat up after about 20 min. of driving and then "conk out". Wait 10 min. and it would re-fire only to shut off again. |

Re: Malfunction
Often spoke about vented gas cap

Re: Malfunction
The car is 100% original except for the diode in the generator cutout and a 6volt Optima battery. Stock ignition, Skip Haney product, about 1000 miles on the restoration, no fuel filter and a new Drake fuel pump.

Re: Malfunction
Due to the lack of quality parts to keep our old ignition systems working reliably. Why not convert to electronic, I understand the GM module will work on 6 volts and replacing the points with a petronics unit is a piece of cake, I'm sure Charley NY or Bubba could supply you with what you need

Re: Malfunction
Excessive opposition to current flow when the resistor heats up. Short out the resistor the next time this happens....

Re: Malfunction
Also. if you have a flexible fuel line the inner lining can collapse under pressure, but idle fine. Had it happen to me. Be blessed & good luck. Ain't flatheads fun!!?? mike
