We have a 1948 farmall super A which generally runs great. However the other day it started sputtering and dying when it was warm and particularly when under load, although occasionally it will shut off when just idling. It does not seem to happen until the engine gets warm. I cleaned the battery connections, cleaned the fuel filter, still happening. Any suggestions of what I should try next?

My 53 was doing the same exact thing, I changed everything electrical on it and still same problem, until my father asked me if I had cleaned both filters in the gas line. Yea, 2 filters, one in the gas tank on top of the cock shuttle and one in the carburator. Remove gas line and unscrew the elbow going into carburator, the strainer will be attached. Cleaned that one after all the other work and tractor now runs like a new one.

Think about it you say it runs well until it gets warm so your problem is fire if it was gas it would do it before it gets warm.

One quick coil check method that will ID a bad coil if it is internally shorted is to feel it. If it is too hot to touch, replace it! Jim

Sounds like a clogged fuel line or a bad coil/condenser.

I am leaning towards fuel because of your last post.

Hi

When it shuts down, try to restart it, if it doesn"t start check for spark. If there is no spark it could be a coil or condenser. Sometimes a bad coil or condenser will cause an engine to shut down and once it cools of it will restart.

Cheers

Russ

I am almost always able to restart it right away but the same thing will happen within thirty seconds or sooner. It seems to be worse at higher RPMS. could it be a fuel issue?

If your gas is over 90 dats old, try new gas.
Just try some premium gas.

The gas is all less than 90 days old. In general is it recommended to run premium in these tractors?

Quoting Removed, click Modern View to see

Premium fuel is not necessary in a Super A. Regular old 87 octane is mo

The only reason for premium fuel is that some gas stations don't put ethanol in their premium fuel, and it tends to have a longer shelf life. If the premium fuel at your station has ethanol in it, don't waste your money.

I personally have had no issues with ethanol fuel or old fuel. None what-so-ever. 5-year-old fuel, with ethanol, untreated, tractor runs like a top...

I bought an old IH 275 swather that had 7 year old untreated gas in it.. about 40 gallons. I was about to drain it, and pour in fresh, but I decided to try starting it with the old. After fixing the electronic fuel pump, it fired up, and my 1st year of hay cutting was paid for.

Most people think gas is worse than 10-20 years ago. I think it's better. I don't know about 5 years, but mine has sat from Nov-April with no problems.
