How to Identify and Fix Common Gardening Problems ?

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.
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.
The most common cause for slow or hard cranking is a poor ground circuit or bad electrical connection. With your John Deere, I would tend to think that it is weak ground either at the cable or where tractor ground/starter mounts. A tractor, in the same manner as a car, uses a DC electrical system.
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.
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.
If it won`t start or fire with spray fuel, you probably have an ignition system problem, most likely a bad ignition coil. However, if it starts and dies, that proves the ignition is working and the problem is fuel starvation. Check the fuel filter first by disconnecting the fuel line from the filter to the carb.
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.
