How to Replace a Craftsman Lawn Mower Primer Bulb
The primer bulb on a Craftsman lawn mower is what supplies the mower's carburetor with fuel. If the primer bulb is damaged, deteriorated or faulty, it will not supply the lawn mower with the fuel that it needs to operate properly. Luckily, you can replace a Craftsman primer bulb with relative ease in order to restore your Craftsman lawn mower to working order again. Does this Spark an idea?

Tips & Warnings
An ideal time to clean the air filter is when you are replacing the primer bulb as you are removing it anyway to get to the bulb.
Beware of not securing the retaining clip completely around the bulb because the retaining clip holds the bulb within the assembly.
