The Exmark Lawn Mower Starts And Then Dies 

If something has gone wrong with a lawn mower and there is no obvious solution, it can be extremely frustrating. You never want to encounter a snag when you are halfway through mowing or just beginning to clean up your lawn on the weekend. The problem of a lawn mower that quits after 30 minutes will leave you wondering what caused it. Though it may seem as though this is a completely random problem, there are several common causes.

There may be problems with plug-ins, clogged pumps, or carburetors that prevent fuel from getting to the engine. When your Exmark mower is plugged in, it won’t work.

The Exmark lawn mower starts and then dies 

Exmark gas-powered mowers are prone to gas getting sour fairly quickly. The shelf life of gasoline is normally about 30 days before it begins to degrade and lose its effectiveness.

Fuel containing ethanol can attract moisture, which can harm your fuel system. Mowing with an Exmark can be costly as moisture evaporates and causes gumming in the fuel system that clogs the system and causes the engine to die.

Aside from clogging the valve, ethanol and water eventually separate from the gas and sink to the bottom. In addition to causing significant engine damage, this can also cause corrosion in your engine.

Here are some tips to ensure you get the most out of your fuel:

Make sure your gas is bought and used within 30 days of purchase

Buy gas at gas stations where there is a lot of traffic

Make sure that your fuel is not left outside where moisture can accumulate

Don’t store fuel in a wet environment

To stabilize your fuel if it cannot be used within 30 days, add a fuel additive. This product is called Sea Foam Motor Treatment. It’s a petroleum-based product, so it won’t damage your engine. In addition to stabilizing your fuel, the product removes moisture and cleans your fuel system.

You can drain your Exmark’s fuel tank to remove old gas. You should replace your gas with fresh gas that includes a fuel additive to clean your fuel system and stabilize it.

Ensure that your old gas is disposed of at the appropriate recycling facility. Fuel should not be thrown on the ground.

Filter and carburetor cleaning

Most lawnmowers have fuel filters connected to the fuel line that can be changed, but some have filters inside the fuel tank that cannot be changed. In case you don’t know where yours is, make sure to contact your manufacturer.

Replacement of the fuel filter is very simple if you have access to it. You’ll need to remove two hose clamps, purchase a replacement filter, and install it. It would be wise to do this first if you can because cleaning a carburetor takes a lot more time and effort.

Nevertheless, if the fuel filter doesn’t resolve the problem, you should remove the carburetor for cleaning. It is helpful to purchase carb cleaners with a small straw included. I will be able to direct a pressurized stream into all of the jets and hard-to-reach areas with this device.

If you disassemble your carburetor, if it is extremely dirty or is heavily built up, you should soak it in carb cleaner or replace it. A local mechanic might also be able to save you a lot of time if you have limited experience working on small engines.

Ensure your Exmark deck is not damaged. Get rid of debris and sharpen the blades. Cutting grass requires full throttle. Make sure you don’t cut wet or tall grass.

Clean carburetors

It’s probably safer to remove the carb and clean it thoroughly if the connectors are not the problem. Gently slide the carburetor off its mounting bolts after detaching the choke and throttle links. Take the whole carburetor apart by unscrewing some parts. Pull the metering plate and gasket off the primer. Clean out any residue inside the ports using your carb cleaning solution now that the internal components are exposed. Afterward, you can wipe it down with a soft cloth. 

Gas tank contaminated with oil

There may be white smoke coming from your mower if you have put oil in the gas tank. It is a very common problem. To fix this, drain the gas tank and fill it up again. For an easier process, you can use a siphon or fluid extractor (here’s a cheap one on Amazon).

Having cleaned the contaminated fuel, run the engine until the mower runs out of fuel. It will allow you to replace it with fresh gas after it has cleared your system.

Problems with the carburetor

Having trouble starting an Exmark riding mower?

There is a possibility that a faulty fuel pump is causing your Exmark riding mower not to start.

Three ports are provided by the Exmark fuel pump (the gas in port, gas out port, and pulse port) as well as two small check valves on the inlet and outlet ports of the pump. 

Bad fuel or gas might be to blame for your problem.

Inspection of the fuel pump for cracks is the fix. Ensure your Exmark riding mower doesn’t run out of fuel by using a fuel shut-off valve.
