What is a snowblower primer and how does it work?
The snowblower primer is a small bulb located on the carburetor, designed to help start the engine by delivering fuel directly into the combustion chamber. When you press the primer bulb, it draws fuel from the tank and pushes it into the carburetor, ensuring that the engine receives the necessary fuel to start. This is particularly useful in cold weather conditions when fuel may not flow as easily.
If the primer is functioning properly, you should feel resistance when you press it, and you should see fuel being pulled into the system. If it’s not operational, you may experience difficulty starting the snowblower, leading to frustration and potential wasted time during a snowstorm.
Why is my snowblower primer bulb not working?
There could be several reasons why your snowblower primer bulb isn’t functioning properly. One common issue is that the bulb may be cracked, damaged, or clogged with debris.
