You care cruising along and cutting the grass when you hit a patch that is a little thicker than normal. All of a sudden the mower begins to bog down and may even die. You are now wondering why it does that?
If your lawn mower works well under normal conditions, it could be a mechanical, electrical or fuel problem. Each of these systems will need to be troubleshot to determine what the problem is. One by one is the best way to proceed.
Since you really cannot put a load on the engine unless you are cutting grass, let’s check some easy things first. Is the spark plug normal looking with a brownish appearance on the electrode? Is the fuel filter clogging up? Are the valves properly adjusted? Is one cylinder not getting spark or fuel?
Check each component to find out what exactly is causing the problem. Some things such as spark will require a spark tester to determine if the spark is good or not. The other items are a visual inspection to see if things are working as they should be.
If you find something wrong, adjust or change the component and retest to see what results you get to ensure that your lawn mower is not bogging down.
