Causes of Your Wright Lawnmower Not Starting

Wright mower will refuse to start if the gas tank is empty.

The reason I bring up an empty fuel tank is that it is a common cause of a Wright lawn mower not starting, but it is often overlooked.

It’s possible to develop a fuel leak without noticing you’re using more gas than usual, forget when you last filled up, or have a broken fuel gauge.

Ensure you have enough gas in the tank for the mower to start and run. Make sure there is no fuel leak and fix the fuel gauge if it is broken. Refill the gas tank on your lawn mower.

The Wright lawn mower will not start if old materials are used.

Fuel for a Wright Lawn Mower

Your Wright lawn mower, whether it runs on gas or diesel, will suffer if you use old fuel. The majority of Wright’s mowers are gas-powered zero-turns, so that fuel and its effects are the primary focus of this manual.

As soon as 30 days after purchase, gas begins to degrade and lose efficiency. The mower may have starting issues as a result of this. Ethanol, a biofuel derived from plants like corn, is mixed into gasoline as an alternative fuel source.

Fuel with added ethanol is better for the environment than regular gas, but it can damage the small engine in your Wright lawn mower.

Because of ethanol’s hygroscopic properties, it draws moisture from the air, which can lead to corrosion in the mower.

When this ethanol and water combination dries, it leaves behind sticky deposits that clog fuel lines and prevent the tiny components in the carburetor from doing their jobs.

Lawn mowers manufactured by Wright require unleaded gasoline with a minimum octane rating of 87 and a maximum ethanol content of 10%.

Do not operate this vehicle with E15 or E85 gas, or any other gas with an ethanol content higher than 10%. They have between 15% and 85% ethanol. The best fuel to use in your Wright mower is fuel that does not contain ethanol, but it can be expensive to purchase.

Use Fresh Fuel in a Wright Mower

You should only buy as much gas as you can use within 30 days due to its short shelf life.

Add a fuel stabilizer, such as Sea Foam Motor Treatment, to your fuel to keep it from deteriorating prematurely if you won’t be able to use it within 30 days.

When you find old gas in your Wright lawnmower, the solution is to drain the tank with a fuel siphon pump. To prevent the fuel system from rusting due to excess moisture, combine fresh gas with a stabilizer like Sea Foam or STA-BIL.

In “Use Sea Foam Additive in a Lawn Mower to Stabilizer Your Fuel,” I explain why I always put Sea Foam in my gas.

Inability to Start a Wright Mower Due to a Faulty Gas Cap

The gas cap on a Wright mower is ventilated so that the mower can breathe. The fuel tank pressure needs to be balanced in this manner.

A vacuum will form in the fuel tank if the vent is blocked or the cap is not vented. That way, no gas will leak out of the tank. Your Wright zero turn won’t start or keep going if the fuel flow is inadequate.

If your gas cap is clogged, you may be able to tell by running your mower with the cap off or loosened. If the mower fires up and runs smoothly, try a new fuel cap.

Let it run for a while longer if you can to see if your mower stops working due to lack of gas. It’s likely that you have a faulty cap if turning the mower on after it automatically shuts off is the only way to get it to start.

To fix this problem, just get a new Wright fuel cap and install it whenever the old one stops venting.

The Wright lawn mower will not start with a faulty spark plug.

There are a few different things that can go wrong that prevent your Wright mower from starting, including a fouled spark plug, an improper gap, or a loose wire. A strong spark is needed to ignite the fuel in your mower. Your mower may not always start because of any of these issues, which can cause your spark plug to fire irregularly.

As a fix, you can use a socket wrench to take out the spark plug. Investigate any signs of use and damage, such as a dirty plug, a burnt electrode, or cracked porcelain. Replacement is required for any dark-colored plug that is damaged or dirty beyond repair.

Otherwise, a wire brush should suffice if there is only a light coating of dirt. I typically only have to change the spark plug. This cheap but essential component is key to maintaining optimal mower performance.

Inspect the spark plug gap according to the engine manufacturer’s recommendation before installing the plug. Connect the spark plug wire to the spark plug and screw it in tightly to ensure a solid connection.

Due to a clogged air filter, my Wright mower will not start.

A lot of dirt and dust get kicked up when you use a zero turn. If you want to keep your Wright mower’s engine in good shape, you should never let it go without an air filter.

When the air filter isn’t regularly removed, cleaned, or replaced, it can become clogged due to the dust and dirt in the air.

When the air filter becomes clogged, it reduces the amount of air that can enter the engine. Your Wright mower won’t start if there isn’t enough air in the system.

Removing dust and debris from the paper air filter of a Wright mower.

  • Take the filter out of the air filter housing.
  • Clean the housing by wiping it down with a dry cloth to remove any lingering dust or grime. Keep the air filter clean and make sure no dust or debris gets into it.
  • Lightly hit the air filter against something solid. You should try to dislodge as much grime from the filter as possible by knocking it around. You shouldn’t clean your filter with compressed air because it can ruin it.
  • The paper filter element must be held up to a light source to determine if any light is passing through it.
  • You can reuse the air filter if you can see light through the paper. If that’s not possible, try switching to a new filter.
    Replace the cover of the air filter housing after installation.

A Wright mower won’t start due to a clogged fuel filter.

To remove debris and other contaminants from fuel, a fuel filter is used to filter fuel as it leaves the fuel tank. If you are using dirty gas or haven’t changed the fuel filter in a while, the filter may become clogged.

If the fuel filter on your mower is clogged, there won’t be enough fuel getting through to the engine. Every year, you should change the fuel filter.

You may have to change the fuel filter on your mower sooner if you use dirty fuel.

A new fuel filter should be installed to fix a fuel system that has become clogged. Wright zero-turns require an inline fuel filter to be installed with the arrow facing the direction of fuel flow.

Because of a clogged fuel line, a Wright lawnmower refuses to start.

The entire fuel system is vulnerable to clogging and damage from stale or contaminated fuel. The fuel lines are a part of this.

Since a clog in the fuel lines is invisible to the naked eye, you must first check the hose by opening and closing the fuel shut-off valve or crimping the fuel line with pinch pliers to initiate and halt fuel flow.

After turning off the fuel supply, cut off the end of the fuel hose that is furthest from the tank and put it in a container. If you want to keep the container below the fuel tank, you’ll need to do some rearranging.

Chemical reactions prevent gas from traveling uphill. Turn on the fuel supply and verify that fuel is dripping out of the hose. Check the fuel flow again, and reconnect the line if it’s fine.

When a clogged line is located, the next step is to clear it. You can do this by disconnecting the fuel line from your Wright mower. The use of carburetor cleaner sprayed down the line can assist in dislodging the obstruction.

The next step is to blow air through the line using compressed air to clear the obstruction. It will take multiple attempts to clear the blockage. It’s time to replace your fuel line if you can’t get the clog out.

Mower fuel lines are readily available for purchase at any hardware store or online. If the fuel lines are dry and cracking, I would recommend replacing them regardless of whether or not a clog is present.

A Wright mower won’t start due to a faulty fuel pump.

Eventually, a fuel pump will stop working. Your fuel pump could fail due to the accumulation of old gas. Your Wright mower won’t start if the fuel pump can’t build pressure and push fuel to the carburetor.

Make sure your fuel pump doesn’t have any leaks. If you can’t locate a leaking fuel line, you’ll want to check the functionality of your fuel pump in a couple of different ways. The first step is to make sure the fuel is actually reaching the pump.

After making sure the fuel pump is getting power, double-check that fuel is actually being dispensed.

Remove the fuel line from the carburetor and set it aside. You should start your mower and observe the fuel hose to see if the fuel is flowing steadily or pulsing.

If the fuel flow from your Wright mower is intermittent or otherwise inconsistent, you should consider replacing the pump.

Wright mower won’t start because of dirty carburetor.

If you continue to use old fuel in your Wright mower, you run the risk of clogging the fuel jet and damaging other small components due to deposits left behind.

The carburetor controls the ratio of fuel to air for combustion in the engine.

Carburetor problems prevent the Wright from starting and running properly. Deconstruct it and clean it thoroughly to get rid of any sticky residue or crusty buildups.

You can clean your carburetor by disassembling its small parts, which should be doable if you have some mechanical aptitude.

You can get a new carburetor or have your local small engine mechanic clean your carburetor if you aren’t confident in your ability to do it yourself.

Take apart the carburetor and use carb cleaner to clean the internal components, such as the float bowl and needle. To learn how to clean your carburetor, continue reading.

You should get a new carburetor if it gets too dirty to clean properly. Find the engine’s model and specification number and give that information to your neighborhood Wright dealer.

Problems with the battery, the cables, or the terminals can prevent a Wright mower from starting.

A dead battery that won’t charge or hold a charge won’t get a Wright going. Problems with starting can also be caused by frayed cables or corroded terminals.

Make sure the terminals on your battery are clean and the battery is attached tightly.

Method: Use a baking soda solution consisting of 2 cups of water and 3 rounded tablespoons of baking soda to clean corroded terminals. A wire brush works great for cleaning the connectors at the end of a circuit.

Put your battery through its paces with a multimeter. Ideally, you’d get a reading of 12.7 volts. If your battery reading is lower than this, you should plug it into a charger.

You can get a better idea of what you’ll need to do to charge your battery by reading the details provided here. It is necessary to get a new battery for your Wright mower if the old one does not hold a charge.

A Wright lawnmower won’t start due to a faulty safety switch.

Multiple protective switches are installed on your Wright lawn mower to ensure the operator’s safety. Mowers have built-in safety switches that disable the engine if the parking brake is on and the levers are in the closed/inward position.

If the mower detects that the operator has left the area, a safety switch will detach the mower deck and turn off the engine. Wright zero-turn mowers may have extra switches for added protection.

If one of these switches breaks, you can forget about getting your mower going.

Check a safety switch with a multimeter. While troubleshooting, it may be necessary to temporarily disable the safety switch.

Never mow the grass without first flipping the safety switch.

Never operate a mower with the safety switch disabled. There’s no telling when you’ll need a safety switch until it’s too late to prevent a serious accident.

Due to a malfunctioning ignition switch, a Wright lawnmower refuses to turn over.

You put the key in the ignition and turn it, but your Wright won’t start. The issue could lie with the car’s ignition switch.

Solution: The ignition switch can be checked with a multimeter. If the switch is broken, replace it.

A malfunction in the charging system prevented a Wright mower from starting.

Your Wright lawnmower won’t start, but the charging system could be to blame. Maintaining a fully charged battery relies heavily on the charging system’s efficiency.

The charging system may be malfunctioning if you find that your battery dies frequently and requires constant recharging. Because the battery cannot supply enough power when this system is broken, your Wright mower will not start.

If your mower’s battery is constantly being drained due to a faulty charging system, you may have trouble starting it the next time you need to use it. A faulty alternator or stator can cause issues. Here I outline how to use an ohm meter to check the functionality of your charging system.

The solution is to have the charging system checked by a local Wright mower dealership or lawn mower small engine repair shop.

It’s likely that you’ll have to keep swapping out appliances and chargers until you find one that actually works if you don’t have any prior experience with charging systems.

Most repair shops won’t accept returns on electrical components, so if you buy something and it doesn’t fix the starting problem, you’re out the money.

If you can’t get help from a Wright dealer, you should find a mechanic who is familiar with charging systems or you’ll be paying to have him or her swap out parts until a solution is found.

A Wright mower won’t start if the operator follows the wrong procedure.

In order to get the best results from your Wright mower, be sure to follow the manufacturer’s recommended starting procedures. The mower might not turn on if you don’t follow the directions.

The choke lever must be correctly set before you try to start the mower for safety reasons in addition to the other precautions.

A cold engine needs to be choked before it can be started. By restricting airflow into the cylinder, the choke increases the fuel-to-air mixture that can be ignited.

Once the engine is warm, the choke should be turned off to prevent the zero turn from sputtering and dying.

Solution: If you want to avoid accidentally triggering the safety features that turn off your Wright mower, review the manual for your model to see how to operate it properly.
