Cub Cadet 72 w/Kohler 12 hp 301A

The tractor was running fine, just using oil.

I did a ring and valve job and when I fired it up it ran like singer sewing machine. After running for about 2-minutes, it died. You can let it sit for a few minutes it will fire up and run great for a minute or two and will die again. I have overhauled the carburetor and set the timing with a timing light.
Could the problem be in the condenser or coil? I had a Ford 8N that had the same problem. I changed out the coil and condenser and fixed the problem.
Thanks, JB 9959

I would check your fuel supply, take off the gas line and be sure you have a good flow.

When the engine quits pull off the plug wire and look for fire to your sparkplug. Hold the wire about a 1/4" away from plug. If you have good fire to your plug you probably have a fuel problem
and I would pull off the fuel line at the carburetor to see if there's a full stream of gas from the tank. If that's look ok the carburetor probably needs a good cleaning. Hal

Try running it with the fuel cap off. Sometimes the vent will plug, causing a fuel restriction.

does that variant of K301 have a fuel pump?

Thanks for all the help.

I rechecked the carburetor float, made adjustments as per manual etc; all was fine.

I checked the gasoline flow to the Carburetor and was only getting a trickle. I removed the bowl and it was filled with a kind of slime. I cleaned it and blew out the fuel line. Put it back together and the tractor runs great. I only had to make a small adjustment to the main carburetor screw.

Thanks again.
