8N stalling on 15 degree hill

Today with the brush hog running the tractor stalled on a hill about 15 degrees. Three times it stalled in about the same area. Each time the tractor would not start till the motor cooled down. Each time I was able to make one pass up the hill and on the second pass, maybe 5 minutes later, it would stall. I took the fuel line off the side and there was a steady stream of fuel. I took off the plug on the bottom of the carburetor and there was a steady stream of fuel. It ran fine until I got on the hill and the motor just died. No skipping etc. Any ideas? Thanks in advance.
 
No I did not. When I get it running again I will check. Stupid question, if it does not have a spark what would cause it to die once the motor is warm and going uphill?

I had a similar problem with my 8-N of stalling when under hot conditions. After a little rest it would start and run again for a while. I finally verified it was an ignition problem .... no spark ... which would return like magic after a rest.

Replacing the ignition switch cured it. I suspect the switch contacts made a poor connection resulting in heating and then a no connection condition. Carry a jumper wire and the next time the "old mule" decides to take a rest ... jumper across the switch.
 
When it stalled did it give any clue as to if it stalled from being rich or lean? Spark usually shuts the motor like you turned the key. Rich might give you black smoke. Any chance the governor isn't working and it's just lugging the motor down? What gear does it happen in?
 
Just this past week while cutting, my 9N sputtered and started to die off. Went to the clutch and it settled out.
Started cutting again and it tried to stall again.
I have a small dash light wired into my switch wires which went off on the second time it tried to stall. Grabbed the switch key and wiggled it; light came back on and back to RPM. Gave a few more wiggles and determined it to be the switch. Rigged it to finish up. New switch in the works. Good luck Sir, Best to all, jac
 
dandb, You said, "Stupid question, if it does not have a spark what would cause it to die once the motor is warm and going uphill?" Not a stupid question, if you don't know something how are you going to learn without asking?
Indiana Ken and gajack gave good advise. However if you find that jumpering the switch doesn't solve the problem let us know, and also tell us if your 8n is a front mount or angle mount distributor.
 
If you find that you have spark when it dies, I would be checking the float, it may be hanging up and not opening the fuel needle when going uphill.
 
"I just pulled a plug and have no spark that I can see. It is a front mount distributor." Did you try bypassing the ignition switch? If you have a multi meter take a voltage reading at the top of the coil with the key on right after it dies. I don't want you to start throwing parts at it, that can get expensive. But if you find that you have voltage at the top of the coil when it dies, I would strongly suspect the coil. They get hot, short out or go open internally and you loose spark.
 
I ordered a new switch from YT, got it today and installed it. The tractor started right up, was able to mow for about 3 hours and it ran fine. The tractor would be a permanent monument in the field if it were not for the people on this forum. Thanks again.
