A Stihl leaf blower primer bulb is a crucial component of a Stihl leaf blower engine. It is a small, rubber or plastic bulb that plays a vital role in the starting process of the engine. The primer bulb is responsible for drawing fuel into the carburetor, which helps to create a rich fuel mixture that enables the engine to start easily. In this article, we will delve deeper into the world of Stihl leaf blower primer bulbs, exploring their function, benefits, and common issues that may arise.
How Does a Stihl Leaf Blower Primer Bulb Work?
The primer bulb works by creating a vacuum that draws fuel from the tank into the carburetor. When you press the primer bulb, it creates a negative pressure that pulls fuel through the fuel line and into the carburetor. This fuel mixture is then ignited by the spark plug, which starts the engine. The primer bulb is typically located on the side of the engine or on the carburetor itself, and is usually marked with a "P" or " Primer" label.
