I have a gas Yard works push mower. It starts with the first pull, as ever, but if I start to mow, and then stop, it will not re-start. It's been slowly getting worse this summer.
Ha! Obviously my cluelessness shows thorough. It's a Tecumseh LEV105. Should it say somewhere on the mower what size engine it is? I couldn't find it, and don't have the manual.
I've put fresh fuel and oil in it, and cleaned the air filter as best I can. Will get a new one next time I go to town.
Could be dirty carb causing problem.
Could be losing spark at coil when hot.
You need to start eliminating area to find out whats wrong.
Try a spark tester on spark plug lead when hot and see if it sparks.
If it doesnt its a coil problem. If it does its carb or something associated with it.
