Reasons Your Bad Boy Zero Turn Mower Won’t Start

Without air, fuel, and spark, you will not be able to get a Bad Boy zero-turn lawn mower to start. Air filters that are plugged, fuel that is dirty, carburetors that are dirty, fuel components that are plugged, spark plugs that are defective, and electrical problems can cause this problem.

There is no fuel in the Bad Boy’s tank

Fuel is necessary to run a Bad Boy mower. Occasionally, we forget to check this obvious reason during the heat of the moment. There might be a simple reason for this, such as forgetting to add fuel, but you could also have developed a leak in your fuel system. 

Solution

There might be a leak in the fuel system that needs to be repaired. This is an excellent resource that will give you more information on how to find a fuel leak on your Bad Boy lawnmower. Your empty gas tank needs to be filled with fresh fuel.

You’re running out of fuel

Expired gasoline can cause significant damage to your carburetors, fuel lines, seals, and capillaries, and cause varnish that will build up on the surface of small fuel ports, which are crucial to the operation of your machine. This decay will cause your carburetor to stop working, as well as damage to your fuel lines and seals. Fuel is one of the most important components of a machine that enables it to start and run properly.

Solution

Gas-powered lawnmowers produced by Bad Boy require a minimum octane rating of 87 and an ethanol level not exceeding 10% in order to operate properly. The ethanol found in most gasoline today, which is an environmentally friendly fuel, can have damaging effects on the small engine in the Bad Boy mower. This is the engine that drives the mower.

Bad Boy Mowers Need Fresh Fuel

Your Bad Boy lawn mower should only be powered by fresh fuel. A fuel additive, such as Sea Foam, can be added to the fuel if it is not going to be used within 30 days. This will ensure the fuel is stabilized and moisture is reduced. Check out this article for more information on the advantages of using Sea Foam in your Bad Boy mower.

Solution

A fuel siphon is a device that is used to drain the fuel tank of your mower when it contains old fuel. If your fuel system needs to be stabilized and cleaned, make sure that you add fresh fuel that includes a fuel additive.

Gas Cap or Rollover Vents Won’t Vent

When the vents in the mower are blocked, there is a high chance that this will happen. I am about to use an example where the tank contains 50 percent fuel and 50 percent air. Then the fuel will continue to be sucked out, but the existing air will need to expand in order to fill an ever-greater volume. As a result of this, a drop in pressure is caused-or, if you prefer, a partial vacuum is produced in comparison to the outside pressure.

Solution

The canister vent line would need to be detached from the gas tank in order to unclog a gas tank that is not venting properly. If there is a blockage in your system, you will need to push it out with a stick or compressed air. As soon as the tank is empty, either leave your vehicle running, siphon it, or open the drain plug underneath it. This will allow you to drain the system.

The spark plug on the Bad Boy mower is bad or the connection is loose

A bad spark plug can cause your Bad Boy not to start when you are not able to generate a spark from it. You may not be able to start your mower if the spark plug is dirty or fouled.

In addition to burnt electrodes, porcelain insulation that has broken, wires that are unsecured, or a gap that is incorrect, a plug with any of these problems can create problems with starting.

Solution

The spark plugs should be removed from your car and inspected to make sure there are no signs of carbon build up or cracked porcelain insulators. These are signs of carbon buildup. Is it necessary to replace the spark plug(s) in your vehicle? If so, make sure that the latest spark plugs are used. It is critical to secure the spark plug wires and ensure that the gap between them is correct to ensure that they are spark-proof.

Lawn mower with a plugged in air filter

Your mower stirs up dirt and grass clippings. Keeping your air filter clean will prevent this from happening. The engine can’t get the air it needs to run when the air filter is plugged in. The computer may shut down if it overheats.

Your Bad Boy’s engine is at risk of serious damage if you run a dirty air filter or no filter at all. Mowers should always be equipped with air filters.

During the mowing season, keep it clean and in proper working order by checking it regularly. Mowing in dry and dusty conditions will require more frequent inspections.

Solution

The air filter should be changed every season and then routinely cleaned.

The fuel filter is plugged

Your lawnmower will likely have problems if the filter becomes clogged. Whether you are having trouble starting the mower, having trouble getting it started, or experiencing uneven idling, this can cause a sputter.

Solution

In order to avoid fuel leaks, it is necessary to replace clogged fuel filters. It is important to install a new filter with the fuel flow arrow pointing in the right direction.

There is a problem with the fuel pump

Fuel pumps are prone to failure over time if they are not maintained correctly. Fuel pumps can be damaged by old fuel sitting in them for a long period of time, causing them to fail. Your Bad Boy will stop working if the fuel pump cannot build up pressure to lead fuel to the carburetor. This is because it is no longer able to push fuel to the carburetor.

In most cases, the problem is caused by improper lubrication, which is the use of the wrong lubricant or not applying enough of it to the machine. There are also times when bearings fail when they are exposed to extreme temperatures. A bearing overload can also lead to failure, for example, when the impeller is overloaded as a result of inadequate flow, causing it to cavitate.

Solution

Seals and gaskets should be replaced if they are old. The manufacturer should be consulted before applying sealant. It is not recommended to apply sealing paste to pumps that have gaskets or seals (O-rings or other seals) because it could cause problems. It is also important to use sealants correctly.

Your Bad Boy has a clogged and dirty carburetor

When you run old fuel through your Bad Boy, the carburetor tends to get dirty and clogged. As part of your engine’s combustion process, your carburetor regulates the mixture of gas and air.

You won’t be able to start your engine if your carburetor is clogged. In order to clean a dirty carburetor and replace any parts that are damaged, you will need to replace the whole unit.

Solution

The carburetor of your Bad Boy needs to be cleaned. If you are mechanically inclined you should be able to handle disassembling it to clean the small parts that make up the carburetor.

By taking the carburetor apart and cleaning both the float bowl and needle of the carburetor, it will ensure that the carburetor is as clean as possible.

There is a possibility that your carburetor is too dirty to properly clean, so I would recommend that you replace it.

Faulty Safety Switch  

There are several safety switches on your Bad Boy lawn mower that are designed to prevent injury to the operator. As part of the manufacturing process, the manufacturer installs safety switches so that your mower will not start without the parking brake engaged before it is turned on.

The mower also has a safety switch that disengages the deck of your mower and shuts down your mower if the mower no longer detects an operator present. This shuts off automatically. It is possible that your Bad Boy has additional safety switches. Bad Boy mowers usually fail to start when these switches fail, so you will have problems starting yours.

Solution

Use a multimeter to test the Bad Boy switch to make sure it is working properly. To identify a faulty switch, the safety switch can be temporarily bypassed for a brief period, but only if you are troubleshooting the unit.

There should never be a time when a mower is operated without the safety switch. Bypassing a safety switch should never be done when operating a mower. You never know when you might need a safety switch, but they can help you avoid serious injury.

Incorrect Operating Procedure 

When starting and operating a Bad Boy lawn mower, certain safety precautions must be followed.

Solution

You should refer to the Bad Boy user manual to ensure that you are operating it correctly to avoid setting off the safety features that would cause your lawn mower to shut off.

In Summary/Conclusion

Eventually your Bad Boy Zero Turn Mower Won’t Start will quit starting, won’t run, smoke, leak gas, give you a bad cut, vibrate, or cause other problems.

You should hire a professional to diagnose and repair your Bad Boy lawn mower if you are unsure how to do it safely.

Your mower will be protected from further damage if you follow these steps. If you are having problems with your Bad Boy lawn mower, you will be able to find help at the dealership or repair shop that sells Bad Boy lawn mowers.
