Riding lawn mower will stop after 15 minutes and is hot.
It is a Troy built super bronco v-twin power 42 in.blade.

Hi,
The 15 min. timespan tends to say it is a fuel problem. Could be the tank vent in the cap, wek fuel pump, clogged fuel filter or tras in the carb at the inlet needle.
Peace,
Clarke

Same problem here... I changed the fuel filter, took the air filter off... The mower is backfiring a LOT, smoke and the like coming OUT of the carburetor... any suggestions??
