Topic: 1940 Ford Starting Problem


21JIMMIE    -- 12-22-2012 @ 1:28 PM
  My 1940 Ford Is Hard To Start After It Has Not Been Started For A While. If It Sets For Just A Few Days I Can Pump The Excelrator And Open The Choke And It Will Start Very Well. If It Is Not Started In A Month Or So I May Have To Pour Gas Into The Carburetor To Start It . What Is My Problem And What Do I Do To Correct It. Thanks In Advance For Any Help Anyone Can Give Me.. HAVE A GOOD DAY.12-22-12

  I don't think you have a problem.....

  Lest you want to dismiss MG's response as inconsistent with the historical reliability of early Ford fuel systems, let me add a comment.

The fuels that we are using today, while adequate in octane to satisfy the needs of our early Fords, do lack the ability to properly vaporize after storage. If you own any infrequently used carbureted device, such as a lawnmower, snow blower etc. you will notice that the quickest way to solve starting problems is to put in fresh fuel. Todays fuels work great when used right away. They do not "keep" well, and any device with a carburetor relies upon vaporization to make a combustible mixture. If you want to be able to only run your Ford every few months, then I'd suggest filling the tank with 80/86 octane aviation fuel, or 100 Low-lead aviation fuel. These fuels do not "go south" as quickly as contemporary motor fuels do.

Be advised however, that you won't be able to simply go to the airport and drive your Ford to the pumps. State and Federal tax laws prevent your local FBO from pumping into automobiles. So...be prepared to simply take a couple of 5-gallon cans to the local airport.
