Ford Jubile

[crankshaull]

I have a 1953 Ford Jubile. It will start and run for a few seconds then shut off. I rebuilt the carb, checked the air filter. Do not have a clue as to what is wrong.
Thanks

When it dies, does it still have spark to all four plugs?
If not, work backwards from there.
Does it still have power to the coil? etc.

Check the fuel flow at the inlet to the carb. Sometimes the screen at the tank shutoff gets clogged.

With the fuel off, remove the inlet fitting, put a can under it and open the valve. You should a good stream of fuel.

Yes it still has spark and power to the coil. Will keep at it until I get it figured out. Thanks for getting back to me.

6 volt or 12 volt?


Don?t guess at the cause of the problem; guessing can get expensive. And leave you breathless chasing every guess.......it could be this, it could be that......just troubleshoot the problem and leave the guess work for buying Lottery tickets.

As soon as the tractor stops running, not 5 minutes later, check for spark and fuel.

You need to answer 2 questions before you do anything else:

With the bolt in the carb bowl removed and the gas on, will the fuel flow fill a pint jar in less than 2 minutes?

Next, get out your adjustable gap spark checker * , open the gap to 1/4", hook it up, turn the key on and crank the engine. Does the spark jump 1/4"? Post back with the answers.

And do not buy a new part for the tractor until you can answer this question: how do I know the part on the tractor is defective?



* Don't own an adjustable gap spark checker? Buy one! Not a test light! Until then, take an old plug, open the gap 1/4" ground it to the head & look for spark. It?s not the color of the spark that counts; it?s the distance it jumps. https://www.amazon.com/AMPRO-T71240-Energy-Ignition-Tester/dp/B00A8FO87S/ref=sr_1_fkmr1_4?ie=UTF8&qid=1513273147&sr=8-4-fkmr1&keywords=ampro+spark+checker
