When the time comes around for your lawn to be mowed, you want to make sure that your lawnmower is ready for some heavy-duty action. Unfortunately, what many homeowners tend to figure out is that not maintaining their lawnmower throughout its downtime can lead to issues such as stalling. Stalling can be both frustrating and expensive if the issue isn't taken care of right away. However, finding the issue should be your number one focus at the beginning. Therefore, to help you get your lawnmower back in working condition, here are four reasons why your lawnmower keeps stalling.
1. Stale Fuel in the Tank
Leaving your lawnmower in the shed and not touching it for days or months can cause some issues when you finally decide to turn it back on again. One of the most common issues with not using your lawnmower for a while is that the fuel within it begins to go stale. Fuel can go stale within as little as 30 days and even faster if it's mixed with ethanol. A great way to get around this issue if you don't have the time to start up your lawnmower every once in a while is to add canned fuel. Canned fuel usually doesn't contain ethanol and thus will last you longer. A more thorough solution is to add a fuel stabilizer to your tank.
2. Dirty Air Filters
It's safe to say that your lawnmower is going to see plenty of dirt and debris during its run. Although most lawn mowers are built to withstand such accumulation of dirt, they all need to be cleaned out every once in a while. Often the reason for a stalling machine is simply due to the air filter not being changed as often. When the air filter is clogged with dirt and debris, it makes it difficult for the engine to receive air.
3. Overheating
When a lawnmower overheats, it begins to stall. Homeowners then tend to fix the issue by turning it off and on only for the motor not to restart again. So, what can be the issue here? There are a variety of reasons why your engine may be overheating; fortunately, most of these are simple fixes. Some of the most common factors that lead to overheating include not having enough oil within the crankcase, not running your lawn mower at full throttle, or simply overworking the machine by attempting to cut dense wet grass.
4. Spark Plug Issues
If you're noticing a significant stalling motion from your machine, then you may have an issue with your spark plugs. Much like the filter, your spark plugs can also be overtaken with dirt, debris, and even oil. This, of course, causes serious issues as the spark plug cannot provide enough air/fuel mixture to get it running properly. The easiest way to fix this is to clean them thoroughly. Just make sure the lawnmower is powered off first.
