The lure of using starter fluid to get a stubborn lawn mower engine roaring back to life can be tempting, especially after a long winter or when the mower has been idle for an extended period. However, before you reach for that can of starter fluid, it’s crucial to understand the implications and potential risks involved. This article aims to provide a detailed exploration of the use of starter fluid in lawn mowers, covering its effectiveness, safety concerns, and alternative methods to get your lawn mower started.
Understanding Starter Fluid
Starter fluid, also known as starting fluid or ether, is a highly volatile liquid used to help start internal combustion engines. It works by igniting more easily than gasoline, providing a quick burst of energy to turn over the engine when it’s cold or when the engine is having trouble starting. The primary component of starter fluid is usually diethyl ether, which has a low flash point, making it easier to ignite in the cold engine.
The Mechanism of Action
When you spray starter fluid into the air intake of your lawn mower, it immediately evaporates and mixes with the air. Upon ignition, this mixture explodes, creating a small, intense burst of pressure that can help rotate the engine’s crankshaft. This action can be enough to get a stubborn engine started, especially in cold weather or after a period of inactivity.
Risks and Safety Concerns
While starter fluid can be effective, it poses significant risks to both the user and the engine. The most immediate concern is the potential for explosion or fire. Starter fluid is highly flammable and can ignite spontaneously in the presence of an ignition source, such as a spark plug. This risk is amplified when used improperly or in excessive amounts. Furthermore, inhaling starter fluid can lead to serious health issues, including respiratory problems and central nervous system damage.
