Starting fluid comprises elements, including volatile hydrocarbons, diethyl ether, and CO2 used to start a stubborn engine.

Frequent usage of starting fluid can damage your gasoline engine. The starting fluid can heat the engine’s cylinder to an unusually high temperature.

In most cases, their high compression rate can cause the engine to ignite too early.
Steps Of Using A Starting Fluid:
You must be careful about the brand of the starting fluid you are using.
Make sure to use a good quality fluid spray to assist you in starting the engine.
Here are the steps that you can follow to start an engine with a starting fluid:
- You will require a screwdriver or a Torx screwdriver for the first step. Gently remove the air filter from the mower by loosening the screws. Some models also have an upper plastic cover on the engine that you need to remove.
- The next thing is to remove the hardware from the air filter housing.
- Once you can see the spark plug ports, you can spray the starting fluid. It is advisable to spray a little, at first, into the carburetor chamber or the spark plug port.
- The next step is to ensure the speed is set to the midpoint if your engine has a flexible option. In addition to that, set the choke to the full.
- Put the pieces and parts back together. Now start the engine by pulling the string or turning the starter key. If the engine starts within three seconds, you are good to go. In case the lawnmower stops after a few seconds. Then the carburetor needs to be cleaned or replaced. Ensure the fuel you use is not a bad quality or water-saturated product.
When To Use A Starting Fluid?

People also use the fluid for diagnostic purposes by identifying the faults in the lawnmowers.
Using a starting fluid for a lawnmower in winter is recommended if you are having trouble starting the engine.

You can save money by learning these steps instead of hiring a professional.
When Is It Not Advisable To Use The Starting Fluid For The Lawnmower?
Using a starting fluid for diesel engines is not recommended as it can destroy the lawnmower.
Starting fluids are also not suitable in a 2-cycle gasoline engine.
If you find something wrong with the lawnmower, it is better not to wait and take it to an expert.
If the expert asks you to change the starting fluid, go for it.
A starting fluid works best with a carbureted engine as the fuel vaporizes through the little openings.
The other sprays do not work as effectively as a starting fluid.
The gasoline is not vaporized, especially when it is cold, hence creating problems.
However, a starting fluid will easily ignite in the cold, helping the engine to start and heating the fuel.
When spraying a starting fluid, you must observe the following safety measures:
- Use eye protection
- Do not use excessive amounts of starting fluid.
- Work in a properly-ventilated area
- Ensure there are no flames or flammable objects around
- Store and dispose of starting fluids properly.
As we have seen in this article, starting fluids are beneficial only when used once in a while.
They are ideal for prolonging the life of the engine battery.
It is excellent to use in winter or cold mornings.
However, if you are using starting fluid for the first time, it is essential to follow these steps carefully.
Whenever you are having difficulties starting the engine, see if the engine needs to be cleaned or it needs to be replaced.
With time, you will instantly become a pro in using the starting fluid for starting and running the lawnmower.
