Farmall Super C (1951)

TAV · Oct 2, 2013

recently inherited IH Super C Farmall. I can get it to fire a start but it dies within about 2 sec. I have gas to the carb. What can I check to keep it running once it starts?

I am assuming it hasn't been run for some time. Turn it over by hand with a crank. You should feel even compression on all cylinders, if not even, you may have sticking valve. Check to be sure you have a good hot blue spark that will jump 1/4". If not you have an ignition problem. I suspect that lack of good fuel to the engine is the problem since you say you have good flow to the carburetor. Did you drain all of the old fuel out, including the carburetor, and replace with fresh gas? If so it seems likely your problem is plugged carburetor passages and a thorough cleaning is in order. Spraying carb cleaner on it isn't going to work, the carb must be totally dis-assembled and all passages thoroughly cleaned. Fortunately these carbs aren't complex and are easy to clean. Good luck with it.

Take the 1/8" pipe plug out of the bottom of the carburetor and make sure that you have good fuel flow through the carburetor, not just to it.

Check your air intake system, sometimes rodents can get in the air cleaner and build their nest thus cutting off the air flow or the oil pot on the bottom of the air cleaner is overfull cutting off the air flow.

If it's running for about 2 seconds all system are working but you're either running out of fuel or air.

An engine needs four things to run

1. Fuel
2. Air
3. Compression
4. Ignition/Combustion

Could also be the condenser. A bad one will cause it to lose spark like you describe.

I am going through a problem with my SC right now after it just sitting for 6 months. Wouldn't start, had fire, gas, but not run. Pulled the drain plug on the carb and a whole lot of white crap came out. Drained the gas tank, gas smelled bad, stale, not like gas should.
Right now I am waiting for a carb kit to come in, plugs, wires, might as well give it a tune up. Lots of fire at the points so will wait and see if I need them or not. Figure spend 100 bucks now and save a lot of screwing around in the middle of the winter when I need the tractor.
I would second checking the carb, seems like they can gum up fast when left sitting.

There may a screen behind the tube fitting where your gas line from the tank connects at the carb. Your carburetor may need to soaked in carb cleaner and the jets blown out with air pressure. Could be gummed up from old gas being left. Hal
