Reasons Your Troy-Bilt Mower Won’t Start

Troy-Bilt engines can be prone to failure for a variety of reasons, so it’s difficult to know what to do when a Troy-Bilt won’t start. To help you diagnose the problem, I have put together a list of all the items you should check.

There is a gas or fuel restriction that prevents Troy-Bilt mowers from starting when the filters and fuel lines are clogged; the carburetor is dirty, or the gas cap is loose. The battery, spark plug, switch, ignition coil, or charging system may also be damaged  Reasons Your Troy-Bilt Mower Won’t Start.

Reasons Your Troy-Bilt Mower Won’t Start

The following items can prevent your Troy-Bilt lawn mower from starting:

• Gas tank empty
• A tank full of old or incorrect gas
• Your gas cap has a plugged vent
• The spark plug may be broken or dirty
• The filter is plugged up
• Fuel pump failure
• There is a clogged fuel filter.
• Fuel lines are clogged with sediment
• Dirty or faulty carburetor
• Batteries that are not connected properly or have a faulty battery
• Switches that fail to function properly
• It is possible that the ignition switch or coil is defective
• Starter solenoid failure
• Wear and tear on the recoil
• Fissures blow

There is a problem with the charging system

A procedure that should have been followed correctly

Need assistance? It won’t start until after winter.

As summer approaches and you drag your mower out of storage, it won’t start. When it does start, it will not run again. Typical of course!

• The following article outlines a ten-point checklist for starting your mower. It is imperative to make sure that you have fuel, oil, and ignition system problems rectified before you proceed, as well as carburetor fault-finding, checking for low compression, and other issues that might be affecting your engine’s performance.

Fuel pump for Troy-Bilt lawn mowers

Unlike other fuel pumps, the fuel pump has three ports: one for gas, one for gas out, and one for pulses. Through a rubber tube, the pulse port is attached to the engine crankcase. As the engine runs, the air inside the crankcase alternately presses and depresses the tube. During this process, pressurized air moves a diaphragm inside the pump and pumps the gas. Overfilling the engine oil can cause oil to enter the pulse port line, preventing it from functioning properly. In addition to a small check valve at its output and input, the fuel pump has two other small ones at its input and output. By installing a check valve, fuel cannot be re-injected into the tank. Failure is possible with these check valves. Ensure the pulse port line, check valves, and diaphragm inside the pump are all in proper working order to determine whether the fuel pump is defective. Fuel pumps cannot be repaired if they are broken. You must replace them.

Have you encountered difficulties with your Troy-Bilt lawn mower?

A lawn mower owned for a long time may begin to work irregularly, not run continuously, smoke, leak gas, give a sharp cut, vibrate, or cause other problems.

The following guide is intended to help you troubleshoot the next problem that arises on a Troy-Bilt mower in order to save time and money.

There is a guide dedicated to common Troy-Bilt lawn mower problems and solutions available online.

A professional can diagnose and repair your lawn mower, even if you lack the necessary knowledge.

It will help you avoid personal injury and additional damage to the mower. If you’re experiencing problems with your Troy-Bilt lawn mower, please contact your local Troy-Bilt dealership or lawn mower repair shop.

The Concept of Compression: What Does It Mean?

In simple terms, compression describes an engine’s ability to build pressure without leaking. A worn sealing ring and valve wear out over time, lowering the compression value of an engine.

The compression tester is what I use in the workshop to test this. Modern engines come with a compression release mechanism, making it easier to start them. For more modern engines, I use a leak-down test. A tested engine holds pressure for a specified amount of time after having air pumped into it.

He was also a mechanic, and back then, car engines could only go about eight thousand miles before they required some pretty heavy maintenance. I remember when I was an apprentice, engines could easily do over 100 thousand miles before they required semi-major repairs.

Advances in engine design and the materials used to make it unlikely that Briggs and Stratton engines will ever require oil changes. Major mechanical failures are unheard of. Failure will occur if the system is misused or not maintained

The battery in your Troy-Bilt mower is dead, the cables are loose, or the terminals are corroded

A dead battery, loose cables, or corroded terminals won’t let your Troy-Bilt start. Ensure your battery terminals are not corroded and that they are securely attached.

FIX: Use a baking soda solution containing 2 cups of water and 3 tablespoons of baking soda to clean corrosion from the terminals. You can clean the terminals using a wire brush.

A multimeter can be used to test your battery. The reading needs to be around 12.7 volts. The battery should be charged if your reading is below this.

The steps and items needed to charge your battery are listed here. A new Troy-Bilt battery will be needed if your Troy-Bilt battery cannot hold a charge. 

Getting Rid of Your Troy-Bilt’s Clogged and Dirty Carburetor

A Troy-Bilt carburetor regulates the mixture of gas and air needed to create combustion in an engine’s cylinder.

Having a dirty carburetor can prevent your engine from getting the gas and air mixture it needs to start and run. You need to replace any failed parts with a clean carburetor.

Clean your carburetor if you have some mechanical ability. Carburetors are composed of many small parts.

In case you are not familiar with cleaning your carburetor, you can have your local small engine mechanic do so or you can have it replaced.

Carburetor cleaner should be used to clean the carburetor, including the float bowl and needle, after taking it apart. These are the steps you need to follow to clean your carburetor. 

Conclusion

It is imperative to check your Troy Bilt lawn mower periodically. Taking proper care of your lawnmower will allow you to extend its life and use it for a long time. If your Troy Bilt lawn mower doesn’t start, there is no need to panic. It is easy to identify the root cause of a problem and how to solve it  Reasons Your Troy-Bilt Mower Won’t Start.
