Is it a mag or coil ignition?
Either way there should be some advance built into the timing spec. Maybe 8 deg or so. You'll need to find the specs. The ignition may be dropping out after it fires. An easy check is with a timing light.
Put a makeshift pointer at the front damper and mark the front damper pulley for TDC and maybe 10 BTDC. I suggest this because the timing marks under the tractor at the flywheel are a pain. Hookup a timing light and fire it. You can do this simple test without the pointer if you like, lots of guys don't like the idea of adding a pointer. If the light stops flashing when the engine stops firing you have an ignition problem. If you go to the trouble of adding a pointer you can use it to time the tractor. If you have a mag I think there is some retard built in on start up with the impulse coupling. Maybe you are too far advanced if static timed to fire at TDC. Maybe you just don't have fuel in the carb or the carb jets are plugged and you just think you've cleaned it.
