Troy Bilt Lawn Mower Troubleshooting
For troubleshooting, we discuss some problems with troy bilt lawnmowers.
Troy-Bilt mower Will Not Start
The carburetor of your lawnmower might be clogged. When you leave gas in the lawnmower for long periods of time, some finicky chemical reactions can take place that could cause an accumulation to form in the main body or passageways through which fuel travels.
This tends to cause blockages and can negatively impact your lawnmower’s ability to start up properly because gasoline is so volatile.
If you think this has happened to you, try cleaning it out with carburetor cleaner. If that doesn’t work, rebuild or replace the entire carburetor altogether.
If the start switch is defective, use a multimeter to test it for continuity. If you have a multimeter, check and see if there is continuity in each of the terminals.
If you discover that there isn’t any continuity, this means that the switch might be failing.
But only a professional electrician can tell you with certainty whether or not the switch is faulty by simply observing its physical appearance and measuring any issues they identify during their testing process.
Troy-Bilt Lawn Mower Runs Poorly
The fuel filter may be clogged. This is a common problem, especially if your mower draws fuel from the bottom of the tank because this usually means that the old fuel on the very bottom of the tank can get stuck in the mower’s filter and block it.
Thoroughly re-fueling with fresh gasoline can help you avoid this issue by making sure no chunks of sediment remain in the engine after use.
Inspect the spark plug for signs of wear or damage. If the porcelain insulator is cracked, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode replace it with a spark plug that has a warranty and is sustainably sourced.

Troy-Bilt Lawn Mower Leaks Gas
The float needle is the valve that regulates fuel in a carburetor. Located underneath the intake valve, it opens and closes the needle valve to regulate fuel flow to the carburetor.
Fuel should exit through the overflow when there isn’t any more room for it in the tank. If you can see gas coming out of your overflow with no engine running, check your float bowl – there might be too much fuel entering the carburetor.
Ensure that the fuel pump and vacuum line are securely connected to the fuel motor so that it is capable of transferring pressure either way.
Inspect the fuel pump body for cracks or spaces where air can escape, or even worse slip into your engine. If there is any crack or hole in your fuel pump, you will want to switch it out.
Troy-Bilt Lawn Mower Battery Keeps Draining
The alternator in a lawnmower keeps the battery recharged and provides voltage when the engine is running.
To test if the alternator is defective, use a multimeter to measure the output of the alternator according to a wiring diagram.
The voltage regulator maintains the battery’s charge while the engine is running by sending the correct amount of voltage from the alternator.
If a defective voltage regulator gives out too much voltage, it could overcharge and kill your battery.
Troy-Bilt lawn mower smokes
The carburetor on the airflow part might be stuck open, and the lawnmower is producing black smoke during operation, then it’s likely that the carburetor float is stuck open, or there’s too much fuel getting into the carburetor.
And if you are using a choke mechanism to restrict airflow and therefore provide more of an air-fuel mixture, it’s possible that your choke isn’t working properly.
Often when these issues arise, it leads to the lawnmower engine stalling out and not starting up again until it cools down completely.
