What is starter fluid?

An ignition starter fluid consists primarily of hydrocarbon (fuel), diethyl ether, and carbon dioxide, which are highly flammable and volatile. In most cases, starter fluid is enclosed in a pressurized spray can.

As soon as the trigger is pressed, the starter fluid atomizes in the direction of the spray. As a result, it is more likely to react with air and mix properly.

It can be harder to diagnose lawnmower engines than car engines because lawnmowers are smaller than cars. Push mowers, and most other mower types are usually powered by two-stroke or four-stroke engines with one or two cylinders.

There can be various reasons why a mower will not start, from a bad spark plug to a lack of fuel.


When to Use Starter Fluid?

As its name suggests, starter fluid starts a difficult-to-start engine. It is beneficial for cold starts in the fall and early spring when the engine is not used often.

It is possible to improve the starting of an engine in cold weather if starter fluid is used. Getting your lawnmower started can be challenging when the temperature is low.
Starter fluid can help diagnose problems with starting your lawnmower if there is an underlying cause.


You can save time by learning how to use starter fluid properly. After reading this blog, you can ask a professional for help if you still have problems.

What are the Required Tools to Spray Starter Fluid?

It is not challenging to spray starter fluid. To do it, you’ll only need a few basic tools:

  • Wrench set
  • Screwdriver
  • Grip Pliers
  • Collector Pan
  • Cleaning cloth
  • Starter fluid

Where to Spray Starter Fluid Lawn Mower?

A step-by-step guide Where to Spray Starter Fluid Lawn Mower:

  • Step 1: Locate the air filter housing
  • Step 2: Remove the air filter and clean
  • Step 3: Find the carburetor chamber underneath
  • Step 4: Spray the starter fluid
  • Step 5: Start the engine and diagnose
  • Step 6: Check, clean, and fix the part that causes the problem

Let’s get started.

Step 1: Locate the housing for the air filter

When working on a riding mower, lift the hood or remove the engine cover. If you have a push lawnmower, you will need to locate the cover’s latches, clips, and bolts. Once you have located the bolts and clasps, remove them. You will need to lift the cover.

The air filter housing can be found on the front of your lawnmower engine. It has an opening shaped like a fin. There is an air intake box and an air filter in this box. The air will then be mixed with the fuel and presented to the carburetor for mixing with the fuel.

Step 2: Take off the air filter and clean it

In most cases, the black cover of the air filter housing is fixed with latches and easily removed. Keep the plastic intact by not breaking it. The cover of some mowers is fastened in place with fasteners. Using a socket wrench, you can loosen them.

You will find a mesh filter underneath the cover. Paper or foamy soft filters are used.

Normally, the filter is easy to remove. Some filters use bolts. Then, remove the air filter by unscrewing the bolt with a torque wrench. The filter is quite delicate, so be careful not to damage it.

You should clean your foam air filter if you have one. The first step is to remove any apparent debris and mud by carefully tapping it. Dry or wet cleaning is both possible for the air filter.

Using a vacuum will allow you to dry clean it quickly. Ensure that the air filter is not damaged. You can also use dishwashing soap or detergent if you have more time. Before using it, let it completely dry.

Pressurized air can also be used to clean it. Air compressors can be dangerous, so use them carefully. The air filter can be damaged quickly if exposed to vital air. You should replace your paper air filter if you have one.

The foam air filter must be replaced if it is damaged or has a paper air filter. Make sure you purchase the right type of replacement filter for your lawnmower.

Step 3: Find the carburetor

The carburetor is often located behind the backplate of the air filter housing. You can easily locate it by following the fuel line from the gas tank. The carburetor mixes the air from the air filter with the gas and sends it to the engine.

Make sure the external parts are clean: Clean the visible ports and grooves of the carburetor with some cleaning cloth if you have the time. You can start your lawnmower more easily if your carburetor is clean.

Step 4: Apply starter fluid

Having cleaned the air filter and carburetor, it is time to use the starter fluid:

Using a clean cloth and some all-purpose cleaner, clean and dry the backplate of the housing.

Identify the intake duct: The carburetor’s backplate has a cutout through which air enters. There will be a breather tube at the end of this intake duct.

The starter fluid should be sprayed into the found opening. As a result, the starter fluid is entering the carburetor chamber.

Step 5: Turn on the engine and observe

You can adjust the idle and choke by adjusting the throttle halfway if it is adjustable. The choke should be lifted to the full position. As a result, fuel intake will be significantly increased.

Turn the ignition switch or pull the starting cord to start the engine. If you add starter fluid to the engine, it should start. Pay close attention to what is happening.

It is a good sign if the mower continues to run rather than shutting down alone. There is usually a stutter accompanied by an engine stopping in most cases.

Step 6: Clean and repair the guilty part

Based on what we observed, we can diagnose the two options as follows:

Within three seconds, the engine stops. The carburetor is malfunctioning. If necessary, it should be cleaned, adjusted, and repaired.

Stalling time between 3 and 30 seconds is option 2. There is something wrong with the fuel, as indicated by this. Either the water is mixed with the fuel, the fuel is dirty, or the gas is harmful.

Fill the fuel tank and carburetor with fresh fuel to solve the problem. The fuel filter should be replaced, and fresh gas should be added.

What are the Pros of Using a Starting Fluid?

Starting the engine with starter fluid is generally beneficial, especially in the winter. As a result, you can save a lot of money by prolonging the battery life.

A lawnmower’s starting fluid must work for a longer period of time.


What are the Cons of Using a Starting Fluid?

Your gasoline engine can be damaged if you use starting fluid frequently. The engine’s cylinder can reach a high temperature when the starting fluid is used. You will likely ruin your engine if you use combustible starting fluid.

Engines with high compression rates often ignite too early due to their high compression rate.


What are the Precautionary Measures for Spray Starter Fluid Lawn Mower?

Eye protection: Wearing gloves and goggles is necessary, depending on your actions. It is possible to get sick from the starter fluid. Visit a doctor if you come into contact with your eyes.

When Is It Not Advisable To Use The Starting Fluid For The Lawnmower?

In the case of a diesel lawnmower, starting fluid should not be used as it can damage the engine. In addition, gasoline engines with two cycles are unsuitable for starting fluids.

If you notice something wrong with the lawnmower, it is best not to wait and to take it to a professional. You should change the starting fluid if the expert recommends it.

Carbureted engines work best with starting fluid since the fuel vaporizes through the little holes. As compared to starting fluid, other sprays are less effective.

In cold weather, gasoline does not vaporize, which causes problems.

It is true, however, that a starting fluid will easily ignite in the cold, aiding the engine to start and heating the fuel simultaneously.
