m a car, it starts and runs for as long as needed.Does not shut off when it gets hotter, at all. But once I shut it off, I will have to repeat the jumping process, again. Can it be as simple as the spark plug? It is about 6 years old

Can you check your battery voltage?

There are several reasons a Craftsman lawnmower may turn over but not start, with the most common ones including the following: Lack of fuel. Dirty air filters. Electrical issues in the ignition system or the starter motor.
Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die
By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.
The most likely cause of a no-start mower after running out of gas is dirt in the carburetor, but other possible causes include: Air locked gas system. Faulty carburetor. Contaminated gas.
Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced. If the starter motor does not run, the motor itself is probably defective.
There may be old or bad fuel in the carburetor float bowl. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner.
If your Briggs & Stratton engine has a spark but won`t run, then it is most likely a problem with the gas or air intake in the engine. The spark on the spark plug ignites the gas in the piston, but if the air filter is clogged or the gas can`t flow, then the engine won`t start.

The gap will be 0.035″ to 0.040″ The wider the gap, the hotter the spark. If your magneto is good and strong, forty thousandths of an inch will work.
