If your lawnmower has been unused for some time, it can be challenging to start. Maybe you have neglected some of the maintenance, you did not properly winterize it, or there is some other reason. When a lawnmower does not start, you need to diagnose the cause. Mostly, the problem lies in a blockage in one of the engine components. Or a problem with the sparkplug. Using the starter fluid, you might start such an engine and diagnose the underlying issue promptly. Show

What is starter fluid, and when to use it?Starter fluid is a volatile and highly flammable mixture that contains rich hydrocarbon (fuel), diethyl ether, and carbon dioxide. Starter fluid is usually enclosed inside a pressurized can of spray. Upon pushing the trigger, in the presence of carbon dioxide, the starter fluid atomizes itself in the direction of the spray. Thus, increasing its tendency to react and mix properly with air. Difficult to startLawnmower engines are smaller relative to car engines, but they can be trickier to diagnose than a car engine. A push-mower and most other mower types are normally fitted with a two-stroke or four-stroke engine, with one or two cylinders. If the mower is hard to start, this can be the result of a multitude of symptoms, ranging from a bad spark plug to bad fuel. When to Use Starter FluidAs the name suggests, starter fluid is used to start the engine when it is difficult to start. It’s beneficial when the engine is not used often and for cold-starts, like in the fall or early spring.

Precautionary Measures
1. What else can you use as a starting fluid?Premixed gasoline can be used as a starting fluid alternative. But if the gas is not premixed, it will dry out the cylinder wall and can lead to damage. WD-40 or carburetor cleaner can also be used, but their emissions are bad. In any situation, it is advised to use proper starter fluid as recommended by the manufacturer. 2. Can starter fluid be used on a diesel engine?No. Diesel engines use a different method to ignite the fuel, and starter fluid can not be used for that type of engine. It can even lead to major damage to the engine. 3. How to adjust the lawnmower fuel intake?The procedure for fuel adjustment is pretty easy and can be performed without any professional help. On the side of the carburetor, you will find an adjustment screw. Often there is a mark on what the default setting is. Start by turn the screw till it perfectly matches this level or mark. Then adjust it until you can see that the engine runs perfectly. Also, check when you ask for more power from the engine that it still works correctly. Starting problems is something that many gas mower owners will experience at some point. They will occur more often during the period when the lawnmower is used less often. Or when the machine is not maintained less frequently. But using starter fluid, you can often start the machine and further diagnose where the problem is. For an engine not starting correctly, mostly carburetor is the main reason. If your machine is older, it can well be that the carburetor should be cleaned, repaired, or rebuilt. It is a good idea to check the fuel adjustment as well. And if possible, check the valve condition and clean them now and then. Where do you spray starter fluid to start an engine?Spray a small amount of starting fluid into the air intake.
Aim the can's nozzle at the air intake from about 12 inches (20 centimeters) away. Spray the starting fluid for about two seconds, then try to turn the engine over. If the engine still doesn't turn over, spray another two-second blast.
