This is what happens if the Purge Primer Bulb - Pressed too Many Times!

VISUALLY EXPLAINED

Pressing the purge primer bulb on your small engine or outdoor power equipment too many times can lead to over-priming. Over-priming can cause several issues, including:

Flooding: Over-priming can force excessive fuel into the carburetor, leading to a flooded engine. A flooded engine won't start and can result in fuel entering the combustion chamber and diluting the engine oil, causing damage.

Difficulty Starting: An over-primed engine may be challenging to start. The excess fuel can create an overly rich fuel-air mixture, making it hard for the engine to ignite.

Spark Plug Fouling: The rich mixture can foul the spark plug, reducing or preventing spark, which is essential for combustion.

Poor Performance: Even if the engine starts, it may run poorly, with symptoms like rough idling, misfiring, or stalling due to the incorrect air-fuel mixture.

Smoke and Excessive Exhaust Emissions: Over-priming can lead to excessive smoke and emissions, as unburned fuel enters the exhaust and burns off.

It's essential to use the primer bulb as instructed in your equipment's manual, usually requiring a few pumps or until you see fuel in the bulb, to avoid these issues. If you accidentally over-prime your engine, you can try starting it with the choke engaged to help clear the excess fuel. If problems persist, you may need to clean the spark plug or wait for the excess fuel to evaporate before attempting to start the engine again.
