There could be a number of different factors that might cause your lawn mower to run for only a few seconds before dying. The most common culprits are issues with the fuel or spark plugs, or problems with the carburetor.
If you’re using gasoline, it’s possible that the fuel is bad, stale, or contaminated. This can cause the fuel to combust more quickly than it should and lead to an engine that runs for only a few seconds before stalling out.
If this is the case, you should replace the fuel with fresh gasoline to solve the problem.
Another possible cause could be an issue with the spark plugs. Spark plugs can get worn out or fouled over time, causing the engine to run poorly or have trouble starting. If the spark plugs are to blame, you’ll need to replace them with new spark plugs.
Finally, it’s possible that the carburetor may be the problem. If the carburetor is clogged or dirty, it can prevent the engine from getting enough fuel, causing it to sputter and die after a few seconds.
The good news is that most carburetors are relatively easy to clean, so if this is the problem, you should be able to take care of it yourself.
Ultimately, the only way to know for sure what is causing your lawn mower to only run for a few seconds before dying is to do a bit of troubleshooting. If you’re comfortable with the basics of lawnmower maintenance, you may be able to diagnose and fix the problem yourself.
Otherwise, you may want to take your mower to a professional for a more thorough diagnosis.
Why does my Troy-Bilt keep shutting off?
It could be a safety mechanism kicking in if your motor is overheating. An engine that is running hot may cause it to shut off in order to prevent any damage to engine components. If this is the case, you may need to allow the engine to cool down before restarting the machine.
