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 MG 07-14-2018 @ 2:45 PM reply profile send p.m. Senior Posts: 1250 Joined: Nov 2009 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.... kubes40 07-14-2018 @ 2:47 PM reply profile send p.m. Senior Posts: 3373 Joined: Oct 2009 Condenser? Even new and NOS are all too often problematic. You would most likely be amazed at how poorly most are.

Thanks for the input.

I found out the hard way about flooding a flat head. Thanks for the reply.

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 Thank You, Harry8750 TomO 07-15-2018 @ 12:33 PM reply profile send p.m. Senior Posts: 7244 Joined: Oct 2009 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. Tom sarahcecelia 07-15-2018 @ 1:29 PM reply profile send p.m. Senior Posts: 1171 Joined: Mar 2013 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. Regards, Steve Lee
