For some, lawn mowing can be a stress reliever, a way to just focus on the greens and let the time pass by. But for some, this activity can be a dreaded task, more so when the lawn mower starts then dies suddenly. Don’t waste a fortune to make another purchase as there are easy ways to fix this situation. Here are the usual causes along with the way to fix and maintenance you can try.
A carburetor, like any other car engine, is the part that mixes the fuel and air to allow internal combustion run smoothly. The left-over fuel turns into residue, which can’t supply enough fuel to keep the motor of your mower running. Take the carburetor out, clean any part that you can and then soak in the carburetor cleaner to get rid of gummy fuel. Allow it to fully dry before assembling back.
When fuel is being used by the engine, the volume is lessened and therefore more air needs to get into the system. If not, a vacuum will occur which results in a stalling mower. This is similar to a human gasping for air.
Check the fuel cap of the mower and see if there are any obstructions in the vent. Remove any clog or debris, and then loosen the fuel cap a little bit just to allow air to pass through. If the situation is the same, then your mower most likely needs a new fuel cap.
The carburetor is the usual suspect of a stalling lawn mower, but the engine has many parts. Lines supplying the engine can also have build up. Therefore, slowly take apart the pieces and clean what you can. Drain the gas tank and fuel lines, and flush all debris out with compressed air or fresh gas. Make sure to be mindful of the order of these parts as you will re-assemble the whole equipment after cleaning them.
Check your spark plug if it is loose, disconnected, or just dirty. With constant use it may exhibit wear or damage such as a cracked insulator, or has a heavy carbon buildup on the surface. If this is the case, replacement of the spark plug is the best option. Replacing this tiny part is a lot better than buying a new lawn mower.
Apart from the interior workings of the machine itself, the exterior part of the mower can also be a reason for the stalling. Check the underside of the mower, the part where grass and other debris can build up. This build up can dull the blade, or make the engine stop as it tries to exert more power in rotating. Carefully brush off and remove any obstruction you see on the underside making sure to take caution of the blades.
Don’t just throw any stalling tools. Try your best, conduct some research, you’ll save yourself a lot.
With the motor stall, try the above steps and you’ll become a professional handyman after seeing it’s working as usual again. With a little bit of cleaning and maintenance, you'll have a freshly cut lawn in no time.
