Reasons Your Snapper Lawn Mower Starts Then Dies

The fuel system and engine of your Snapper mower will malfunction if you use gasoline that has been sitting or stored for a long time.

There is ethanol in most gasoline sold today. It is a corn-based additive used to reduce the impact of gasoline on the environment.

Ethanol can be used in your vehicle, but not in your Snapper mower’s small engine.

Because of this, you should make sure your unleaded gas does not contain more than 10% ethanol. As ethanol evaporates, it pulls moisture from the atmosphere. When moisture evaporates, it can leave a sticky substance in your Snapper mower that reduces fuel efficiency.

Fuel tanks separate ethanol from gasoline over time as it sinks to the bottom. Using this mixture can lead to your engine overheating and damage.

Check your mower’s fuel level regularly. In the event that you won’t be able to consume the fuel within 30 days, add a fuel additive to stabilize it. I use it in every tank of fuel, regardless of how long it sits.

With Sea Foam Motor Treatment, I not only stabilize the fuel, but it also reduces moisture and has cleaning agents. The advantages of Sea Foam in lawnmowers are described in my article.

The gas bowl needs cleaning

In many cases, you can solve your problem by simply cleaning the bowl, which collects dirt and moisture that slips past the gas filter. You may need to strip down and clean your carburetor if grit has entered the jet.

It’s easy to find fast-acting WD40 carb cleaners on Amazon. In the tiny passageways of the motor, WD penetrates and breaks down varnish deposits.

See below for instructions on cleaning the fuel bowl. Usually, one bolt secures it, and that bolt can play an instrumental role in the fuel feed system. Generally, stale gas isn’t removed by cleaning the bowl, so it won’t go. It is necessary to empty and fill the tank, carburetor bowl, and carburetor with fresh gas.

Dirty Snapper Mower Carburetor

It is the carburetor’s main job to regulate the amount of fuel mixed with air to create combustion in your engine. The carburetor can cause your mower to start and then die if it is not operating properly.

Running old fuel in your carburetor causes the carburetor to accumulate gummy deposits and sticky deposits. The restriction of fuel flow will result from this damaged carburetor component.

Snapper Mower Gas Cap is damaged

It is possible for a Snapper mower to shut down if its gas cap is no longer venting, allowing air to pass through. An engine cannot receive gas when the vent in the gas cap is plugged in.

Check if your Snapper mower is dying with and without the cap for periods of time.

A fuel cap problem occurs when you remove your cap and your mower starts up and runs, but eventually shuts down.

A new fuel cap can be used to repair the clogged fuel cap or to remove the clog.
