8N tractor with intermittent stopping

Tractor was stopping, esp. on rough ground and on hot days. Local advice was vapor lock, bad coil, or ignition switch.

Replaced ignition switch, coil, and condensor with no results. Found some rust in the glass bowl on the gas shut off. Apparently rust particle would block main jet when tractor was operated on rough ground.

Thanks for the advice. I think Siinc was right. Sandblasted the inside of the carb and put an in line filter on the gas line. tractor has run for over four hours. (:>)

I'll try another coil and then replace all the wires. running out of options. Replaced the igniton switch, the coil, condensor and points, added an in- line filter, sandblasted and cleaned the carb float chamber.

Gads and this is a simple machine.

Neighbors 9N does the same thing. Think I know where to look first now.

It seems the old filters weren't preventing the rust/sediment from plugging the main jet? Not sure if the filters were adequate to deal with the rust?

Thanks for the warning - will have to watchout for manifold heat on the filter.
