Why Is My Lawn Mower Engine Popping

So, why is my lawn mower engine popping? When fuel ignites beyond the combustion chamber of the engine, a popping noise or backfire occurs. Your mower may be operating normally and without incident until you hear the backfiring. While this explosion may cause you discomfort, there is nothing to fear. However, if left ignored, the source of this backfire might become harmful to the motor of your mower.

You must do extensive research to determine what caused the engine to backfire. Once you’ve determined the problem, resolve it so that your mower may resume regular operation. Typically, the popping sound happens when you start or stop the engine. Having a working knowledge of the popping sound and how to cope with it is beneficial.


What is Lawn Mower Backfire?

Your gas mower’s engine has a combustion chamber where controlled explosions produce power. When everything is operating normally, these explosions are not audible, but if an explosion occurs beyond the combustion chamber, the sound of backfiring is audible. This suggests that the explosion occurred in an area where it should not have occurred, most often in the exhaust system. 

Popping Sound Before Shutdown

When you hear a lawn mower engine make a popping sound, you may deduce what’s wrong. If this occurs when the engine is idle or while it is being turned off, you may be slowing it down too rapidly.

When you quickly shut down your motor while mowing, some gas may leak into your muffler. Once there, it will ignite and generate a backfire. Avoiding this is as simple as progressively lowering your engine speed. Allowing the engine to idle for 15 seconds prior to shutting it off may completely remove the backfire.


Fuel Issues

If your engine backfires while you’re mowing, there are a few probable reasons. When there is too much air and not enough fuel in the combustion chamber, low fuel pressure may result in a backfire. On lawn mowers with speed options, this may be corrected by simply raising the speed and hence the fuel supply. Another possibility is that the gasoline pump has failed or that the fuel filter has become clogged. If altering the speed of your mower does not help, then investigate for probable issues with those components.


Engine Problem

Another probable cause is a timing issue. If the spark that ignites the gasoline does not occur at the appropriate moment, your engine may backfire. Your engine may need a tune-up, which may involve spark plug replacement. If it’s been a while since you’ve given your mower any care, schedule some time to give it some TLC and backfiring difficulties may resolve.

While a lawn mower engine is not as complicated as a vehicle engine, it still need regular maintenance. Spend some time each summer prepping your lawn mower and you may prevent dealing with engine backfires.
