If you have a relatively big yard, a Troy Bilt lawnmower is one of the go-to tools for easy landscaping and grass-cutting. But what should you do if you encounter some issues with your mower?
Here, our experts dive into the solutions when your Troy Bilt lawn mower won’t start.
Issue #1: Gas Tank Isn't Enough or Empty
At any given time, your lawnmower is run by fuel or gas. Most lawnmowers are gas-powered, and it is easy to identify why they won’t start. The gas task is empty or doesn’t have enough gas to make it start.
Fix: Fill With Fresh Fuel
It is essential to check your gas tank from time to time. To keep your Troy Bilt running, a good recommendation for that is to fill your gas tank with fresh fuel. It is also to keep your motor good maintenance to extend the life span of your Troy Bilt.
Issue #2: Old or Wrong Type of Gas
As mentioned, you have to fill your Troy Bilt with fresh fuel. However, if you have skipped cleaning your yard for a long time and haven’t touched your lawnmower, it will also affect the quality of your gas. Filling your gas tank with the wrong type of gas can also damage your lawnmower’s motor.
Fix: Drain Fuel Tank and Fill With Fresh Fuel
If you accidentally filled your gas tank with the wrong gas, all you need to do is drain your fuel tank and fill it with the right fresh fuel with a fuel additive. This helps clean and stabilize your fuel system, especially if you have put the wrong fuel.
Issue #3: Gas Cap Won't Vent
It’s possible that your vent is plugged, giving no fuel to your engine. To identify this issue, you need to remove your gas cap to see if it is venting. If it is venting, place the lid back and run it continuously. This is to check if your lawnmower starts to spit and shuts down automatically after.
Fix: Clean the Gas Cap
If your lawnmower shuts down after checking the vent, your vent is bad since there is no fuel supplying the motor. If this happens, your vent is clogged, and you need to clean your gas cap. If cleaning doesn’t succeed, you need to replace your gas cap.
Issue #4: Damaged Spark Plug or Loose Connection
One of the reasons your Troy Bilt may have problems starting up is your spark plug. Either you have loose connections, dirt issues on the tip, or might have been damaged over time.
Fix: Remove and Check Spark Plug
Check your spark plug if it is not properly gapped, if there is carbon build-up, especially on the tip or if it might have a broken porcelain insulator. If there are damages, replace the spark plug with a new one.
Issue #5: Plugged Air Filter
Grass clippings and dirt may get stuck in your filter as time passes. If this happens, air passage to your engine is minimal. Hence, this will make your engine overwork and leads to overheating and shutting down. This will also damage your lawnmower’s internal engine, which may cost you a lot more than finding a new filter.
Fix: Remove and Check Air Filter
Remove and check your air filter for dirt and grass cuttings build-up. Tap your filter onto a hard surface to clean it. Since this is a paper air filter, you can hold it up to see if light passes through it. If not, then it’s time to replace your air filter.
In another case, for a foam filter, you can wash it with dish soap. Rinse your foam filter and air dry it lying flat. If your foam filter has already been torn or brittle or has brown spots, our team recommends replacing it with a new one.
Issue #6: Bad Fuel Pump
Your Troy Bilt’s fuel pump goes bad over time. One reason is your old fuel that’s been sitting in there. It may cause damage to the internal parts of your pump that later on will leak, and the engine will not receive sufficient fuel to start.
Fix: Replace the Fuel Pump
If this is the case, you need to replace your fuel pump.
Issue #7: Plugged Fuel Filter

Issue #8: Clogged Fuel Line
A clogged fuel line is caused by old or bad fuel. That’s why it is important to fill your tank with fresh fuel. A clogged fuel line can stop fuel from passing to your engine, and this causes your Troy Bilt not to work.

Issue #10: Bad Battery, Loose Cables, or Corroded Terminals

Issue #14: Bad Recoil
