What to do if Troy-Bilt TB130 Lawn Mower engine runs erratic?

If your Troy-Bilt lawn mower engine is running erratically, check the spark plug boot to ensure it is connected and tight. A blocked fuel line or stale fuel could also be the culprit. Additionally, inspect the gas cap vent for blockage, and check for water or dirt in the fuel system. Make sure the unit is not running with the choke applied.
