Farmall H quits running.

I have a 1947 H, after running from anywere between 1/2 hour to 1 minute it stalls. It has fresh gas in it with dry gas, I put on new plug wires and plugs, glass seditment bowl is clean, the manual said to clean a screen in the carb, checked mine hopeing that was the problem, not plugged at all.
Other than points and condenser or rotor, which I havent really checked what could make it keep stalling? I would think it would be a fuel problem! dunno. I did pick up a carb rebuild kit last fall, but havent put it on yet. I really like the tractor, but this is fustrating. I have two Ford diesel tractors that do the work, but I wanna get this H running right so it can be used if needed, without having to leave it in the field until the next day when it will start so I can get it back to the barn! thanks j
 

The next time it stops, immediately get off and feel the ignition coil. If it is too hot to touch, or at least very warm, there is your culprit. If the coil is not hot, then remove the fuel tank cap. If you hear a suction sound while removing it, that means the vent is plugged. Easiest fix is a new, vented fuel cap.
 
I have checked the fuel cap for vapor lock and it did not make a sucking sound. However I did not check the coil! I thought a coil either worked or it dident, or could it be intermitten? Also after a few minutes the tractor will start right up again, but only run for a few minutes. I will check the coil after I run it and it quits again. Thank you. J
 

Yes, a coil can be just fine for the first several minutes of running, and then just quit. Let it cool down and it's just fine again.
 
Check the bottom of your gas tank. I have an H that did a similar thing. Found junk in the bottom of the tank that would plug the outlet hole for the gas. Took me alittle while to figure it out because it was so random, but cleaned the tank and haven"t had a problem since. Just a thought.
 
Thanks again, I will check it tomarrow. Im looking at a Temco catalog for a price on a coil but dont see any coils listed. I will call them. Or can I order on here on yt parts? JayinNY
 
Yes I thought about that, but when it quits the sediment bowl is still full of fuel??? I would think it would be empty like its running out of fuel? Anyhow I was thinking of draining it just to be sure. Thanks J
 
Just becuase the sediment bowl is full doesnt mean that its not clogged becuase the gas is sucked out from above the fuel bowl, when it quits running check for fuel flow, but i suggest taking the tank off and washing it out with a power washer and let everything drain out and dry before putting gas back in, its pretty easy to do and could be another simple fix. Good luck and if you ahve any other clues just post up!
 
Rusty's right about the coil...and for the record, the sediment bowl will have gas in it whether you've got gas or not. If it's not the coil, a dried out condenser will make it behave that way too
 
My 2 cents worth: I wouldn't pursue spending money on a coil until I checked the fuel supply. Old story: Years ago my dad had a nice 56 IHC pickup. It'd run great then suddenly die. Sooner or later it'd re-start and run and then sometime die again. The mechanic carefully drained down the carb. and found a weed seed. It'd float then plug the fuel flow, then re-float. I think fuel supply might be first to check. Good luck.
 
i have a farmall b that would die ocassionally without warning. then restart fine. finally found the problem. soybean was in the fuel tank. would cover the fuel inlet, tractor would die, then the bean would roll off the inlet.
 
When it quits running check for fire to your sparkplugs ASAP before it has a chance to cool.
If you have fire to your plugs and it won't start you probably have fuel blockage. Pull the fuel line at the carburetor and see if you have a full stream of gas from the gas line. Hold a clean container beneath the line to catch the gas and any dirt or rust. If there's not much flow from the line look in the gas tank with a good flashlight to see if the outlet hole is covered with dirt, rust or seeds. Hal
