Understanding the Role of the Spark Plug in Your Craftsman Power Washer
What is a Spark Plug?
A spark plug is a small device that ignites the fuel-air mixture in the engine’s combustion chamber. It generates a high-voltage electric spark, which ignites the fuel, powering the engine and enabling the power washer to operate effectively.
Why is the Spark Plug Important?
The spark plug is essential for:
- Starting the engine quickly
- Maintaining smooth engine operation
- Ensuring efficient fuel combustion
- Preventing engine misfires or stalling
- Extending the overall lifespan of the power washer
A faulty or worn-out spark plug can cause starting issues, poor engine performance, increased fuel consumption, and even engine damage.
