Re: My new 1938 Tudor
Nice 38. Skip Coil and a tested condenser time.

Re: My new 1938 Tudor
Do the easy things first, disassemble and clean carb innards. If you see sediment in the carb bowl it means dirt from the tank or line. Change to another coil and condenser. Then try. How hot was it when this happened? I thought Nova Scotia was up by the North Pole.

Re: My new 1938 Tudor
Lindsay, Contact Skip Haney in Florida for a rebuilt coil. His rebuilts are better than original, and are show quality as well. The cause of your breakdown was the old coil heating up and shorting. Once it cooled down sufficiently, it fired up for you again till it heated up again. Don't even think about any other coil, use Haneys. He will advise on the correct condenser to use with his coils also.

It sounds like a fuel delivery problem, but it could be ignition, too. When it starts to run badly, stop engine, pull a spark plug wire and hold the connection about 1/4 inch from the plug connection. Crank engine over with ignition switch on and you should see a strong spark. If weak and yellow you could have ignition problems. If ignition seems OK, disconnect fuel line from carburetor, place fuel line in a container of some sort and crank engine over WITH IGNITION OFF. You should see strong pulses of gas as the engine turns over. Weak dribbles indicate fuel problems. Since the pump is new, consider stopped up fuel lines (likely if the car has set up for long periods), leaks allowing air to be pulled into the pump instead of fuel, or a worn fuel pump push rod. Give us more information if these suggestions don't point you to a cause. |

Re: My new 1938 Tudor
Wow! A nice looking survivor. I think the coil, condensor and gas delivery suggestions already made are your best things to check first.
I would not leave my driveway with any of my old Fords without a coil rewound by Skip Haney. No matter how nice those original coils look, internally the insulations used back in the day have deteriorated. Once expansion occures from the effects of heating, windings will begin shorting out.

Re: My new 1938 Tudor
I will have to do the coils
It will sit and idel for ever and rev up with no load but does want to go very far. Seems like fuel. I borrowed a pump diaphram and it didn't change. The diaphram in the pump looked new. I flushed the cooling system and and engine. I was hesitant about the stirring up oil sludge but did did 2 changes in a row, both came out dirty and now looks clean. The coolant was foamy and brown. I have to adjust the brakes better. There is a great story with the car which I will tell later! Thanks Last edited by 36coupe; 07-26-2014 at 06:11 PM. |

The car was running cool. Found temp sender laying on top the head not hooked up. We are having a hot summer which is totally bearable compared to points south |

It almost seems like it is missing at times. A couple of times I barely hit the starter and it fired right up but not most times. |

Re: My new 1938 Tudor
I stripped down the carb and it was fine. I am running a little rich.
Do I lower the float to lean out the carb some? I went 5 miles and it worked great and then started to run poorly and stalled. I had to wait a while for it to cool down and then made it home. Thought the problem was the choke coming on a little bit causing it to run rich. The next drive it stalled in the neighbours driveway and and we checked the voltage at the coil and it was 3 volt and no spark rolling over. I still think I have a coil overheating problem and a minor problem of the carb running rich. |

Re: My new 1938 Tudor
Lindsay, 3 to 4 Volts at the coil is correct. You have a resistor up over the steering column on the dash. The function of that resistor is to reduce the voltage going to your coil. Bite the bullet and get a rebuilt coil from Skip.
One thing at a time. Don't mess with the carburetor, it has nothing to do with your coil problem and will only confound diagnosis for those of us who are trying to help you.

Re: My new 1938 Tudor
All old cars, particularly those which have set for a very long time, need a fuel filter in the line as close to the tank as possible. Today's gas is a good solvent, and will loosen sediment and varnish which will impact the whole fuel system. Inline filters are not expensive, or hard to install. Install barb connectors on the cut ends of the fuel line to prevent fuel or air leaks. The filters have expanded ends for the same purpose. Carry an extra in the car at all times if the one in the fuel line clogs. Most "barn find" cars will go thru several filters until the system is free. The alternative is to remove the tank and have it cleaned, which is a big job.
