I know this is a repeat question. I have a 1945 farmall A. It has ran great all year and this past week my son took it out and while driving it just stopped. I let it sit and it fired right up. I moved it to the barn and let it sit for a few day and it ran like a watch for a while before I shut it off.Now when I start it it only runs for like 10 minutes the dies. It turns over but it will not fire. I smell gas and the tank is full. Do these old ladys have a fuel filter that needs clean out or is it cheap gas?

Sounds like the coil may be on it's way out. They are cooled by oil internally, over the years the oil slowly leaks out they overheat and fail.
After sitting for a while they cool and continue to function.
To check it, after the tractor dies after 10 mins of running, place an ice pack on the coil. wait a few minutes and it should start right up, if that's the case the coil needs to be replaced.

If you have a magneto, your coil is not oil cooled. A battery ignition coil can be oil filled however.
I would check to see if it might be a fuel problem. When it quits, take off the gas cap and see if it will start again. Sometimes the vent holes in the cap get plugged and the vacuum starves the carburetor for fuel.

Hi, your problem sort of indicates the same type as I had a while back. Take the gas line off the connection at bottom of gas tank and push a piece of wire up through the small fitting into the tank.Mine was clogged in that area with what looked to be old leaves. Cheers, Murray///Post back when you find your problem.

Just tell me where you get the idea the coil is filled with oil. Those coils do not have any oil in them and its guys like you getting thiongs all mixed up and passing bad information so if you dont know please dont comment.
This sounds very typical of a dirty fuel tank. Something gets in there just right and it only blocks fuel off occassionaly. On my A it drove me crazy cause the tank was clean but it was still acting this same way and sometimes it was fine and other times it would act up. Mine had a little flake of paint that I have to assume fell off the cap that was causing all the problems. I finally got that out of there and it was all good to go again.

Gene, Mag coils do not have oil in them, but many can style coils do. The newer the more likely to be "potted" with a tar like material, or epoxy, but the tar like material can heat to an oily consistency and leak out when hot. Jim
I left the key on once and when I returned the oil-filled can had blown the top off covering the right side of my 140 in oil. My bad luck the points were closed at the time of my stupidity. That was about twenty years ago. (Turned out it was a 'use with resistor' coil with no resistor. That boo-boo was done by my brother.)

If the coil is too hot to hot your hand on when it shuts down, throw it away. A new one will solve your problem.
If you can hold your hand on it, check the gas supply system. Make sure gas tank is vented as mentioned.
AYE AYE SIR !!
Had the same problem on my 300, coil was so hot you couldn't hold your hand on it, so I replaced the coil. The first time it happened I iced it down & the tractor started right up.
The original poster stated he smelled gas so I incorrectly assumed it must be a spark problem. I didn't know he had a magneto, and yes, magneto coils do not have oil in them like a battery ignition coil does.
anyone needs me I'll be over here in the corner. :roll:
