Our experts will help you solve the problem when your Troy Bilt lawnmower won’t start.
Issue 1: The Gas Tank Isn’t Full Or Enough
Your lawnmower can run on fuel or gas at any time. Gas-powered lawnmowers are common and easy to recognize why they don’t start. It is either empty, or it doesn’t have enough gas to start.
Fill With Fresh Fuel
Regular gas tank inspections are essential. It is a good idea to keep your Troy Bilt running by filling your tank with new fuel. To extend the life of your Troy Bilt, it is important to maintain your motor well.
Issue #2: Wrong Or Old Types Of Gas
You must make sure your Troy Bilt is fueled with fresh gas. You can also damage the quality of your gasoline if you don’t clean your lawn for a while or haven’t used your mower in a while. The wrong gas can cause damage to your lawnmower’s motor.
Repair: Drain The Fuel Tank And Fill With Fresh Fuel
You can fill your tank with the correct fuel additive if you have accidentally filled it with the wrong fuel. This will help stabilize and clean your fuel system, especially if the fuel was incorrectly poured.
Issue #3: Gas Cap Won’t Vent
Your vent could be blocked, preventing your engine from getting fuel. To determine if your gas cap is clogged, remove it. If the gas cap is not venting, you can place it back on and continue to run it. This is done to see if the lawnmower begins to spit or shuts off automatically.
Cleanse The Gas Cap
Your lawnmower will shut down if it has been checked for fuel. If your lawnmower stops working after checking the vent, it is likely that your gas cap has become clogged. If the cleaning fails, it is time to replace your gas caps.
Issue #4: Loose Or Damaged Spark Plug
Your spark plug could be a reason your Troy Bilt is having trouble starting up. You might have loose connections, dirt on the tip, or damage over time.
Repair: Check And Remove Spark Plug
If your spark plug isn’t properly gapped or has carbon buildup on the tip, or if it may have a cracked porcelain insulator, check it. Replace the spark plug if there are any damages.
Issue #5: Plugged-Air Filter
As time goes by, dirt and grass clippings can get lodged in your filter. This can cause your engine to have reduced air flow. This will cause your engine to work harder and eventually shut down. This can also cause damage to your lawnmower’s internal engine. It could cost you more than a new filter.
Repair: Take Out And Check The Air Filter
Check your air filter for dirt or grass cuttings. To clean your filter, tap it onto a flat surface. You can test it by holding it up, as it is a paper filter. If it is not, it’s time to replace the air filter.
Another option is to wash a foam filter with dish soap. Your foam filter can be rinsed and dried flat by air drying. Our team recommends that you replace your foam filter if it is damaged, brittle, or has brown spots.
Issue #6: Bad Fuel Pump
Over time, your Troy Bilts fuel pumps can go bad. Your old fuel could be the reason. The old fuel could cause damage to your pump, which can lead to a leakage that will result in the engine not receiving enough fuel.

Issue #9: Clogged Carburetor
Old and dirty fuel can cause a clogged carburetor. Your lawnmower will not work if your carburetor becomes clogged.

Issue #12: Ignition Coil Or Defective Ignition Switch
If your mower doesn’t start when you turn it on, either the ignition coil of the switch is the problem.
