What kind of fuel to burn in a 1940 Ford Flat head? I have problems every time the weather gets hot. I have replaced everything I could. Carburetor (twice) I tried a Phenolic Spacer under Carb to intake manifold. New old stock points, rotor, cap, and condenser. I have had coil rebuilt by Skip Haney. Replaced all plug wires and plugs twice. I am still running a 6 volt system. The base of the carb is cool to the touch after running motor up to temp. Problem is it runs for a while then it will not restart until it has sat for a while and cooled down. I am now running ethanol free fuel at $10.00 a gallon and it seems to be doing the trick, but can not say this is the answer., any ideas would be appreciated. Thank you.
Thank You, Harry8750

When you try to restart the engine, does it turn over slowly? I'm thinking that the starter motor might be drawing too much current away from the ignition circuit....

Condenser? Even new and NOS are all too often problematic. You would most likely be amazed at how poorly most are.

Sounds like it could be the coil resistor.

tell us your starting procedure for a warm engine. flatheads do not like a shot of gas on a warm engine, just turn switch on and hit the starter button, no pumps on the carb

Motor turns over easily, normally starts with engine turning over one time. Thanks for the input.

I know what you are thinking, I do not use choke, or give it any fuel to start warm engine. I found out the hard way about flooding a flat head. Thanks for the reply.

I had Skip Hanney check three condensers for me and have tried different ones after he tested and approved them. It seems like it always comes back to fuel, plenty of hot spark, and all new tested electrical parts. Thanks again Mike I appreciated your input

If you have good spark, your problem might be flooding. The most common causes are float level and power valve or gasket. Check your plugs for wet plugs, when the engine is hot. Try starting the engine with the accelerator pedal to the floor. The rubber tipped needle valves need the fuel leve set 1/16" lower than stock. I like to set it there even with the steel needle valve.

Ethanol fuel has alchohol in it (about 10%) and alchohol absorbs WATER!, which is not good for your fuel system. It will do the same thing that the old non silicone did to your wheel cylinders- pit and rust them, because that old brake fluid was Alchohol and Glycerine. Use leaded fuel. It has no alchohol in it!Thats what they used in the day( 50's,60's, 70's, 80's, and that was the only fuel for all cars, at all gas stations, High Test, or Regular! You can google and it will show you where you can get it in your area. As a very last resort, go to the local small airport. All of the single engine and multi engine aircraft use it-Ask for 100 low lead. It's a little more expensive than the gas station though, because it's 100 octane!How do I know you say? I'm a private pilot and have an airplane, have to use it,and can get it at all small air ports in Florida. Now if you do that, don't be so foolish as to go to a large commecial airport. They have it, but you won't be allowed to drive to where it is! I have about 5 gas stations within 8 miles of me where I can buy it. One of them is a Sh*ll station.
