How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.
A starter malfunction can have different causes: Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically.
The starter can spin without engaging with the flywheel , or jam in engagement. In an inertia starter, dirt in the spiral Bendix thread is the usual reason for it not engaging. Remove the starter (See Checking and replacing the starter motor ) and clean the gear thoroughly with petrol and a paintbrush.
Typically, a new starter will make noise when it`s positioned too close to the ring gear on the flexplate or flywheel. Installing thin, steel shims between the block and starter is the method to eliminate the noise. Another problem that may cause starter noise is an out-of-round flexplate.
If you turn the key and hear the starter spinning madly but don`t hear the engine cranking, then the pinion gear isn`t thrusting forward. If you turn the key and hear crunching and gnashing, then the teeth on the pinion gear, or the flywheel, or both, are probably damaged.
The starter solenoid is an electromagnetic switch that engages the starter motor. How can I tell if my starter solenoid is bad? If you`re having trouble cranking the engine over but the battery is charged, or if your starter won`t disengage after starting the engine, it`s likely a starter solenoid issue.
The Bendix system places the starter drive pinion on a helical drive spring. When the starter motor begins turning, the inertia of the drive pinion assembly causes it to wind the spring forcing the length of the spring to change, and allowing the pinion to engage with the ring gear.
Flywheels play an important part in the starter process of a vehicle. When you turn on your engine, the starter motor pushes a gear towards the flywheel. This gear meshes with the flywheel`s teeth to make the engine turn over.
If one or more of the flywheel`s teeth are damaged or broken, then the wheel can`t engage with the starter motor. You might need to try a few times to get your car to start, or it might not start at all.
Freewheeling occurs when you crank the engine and simply hear a whining noise without the engine cranking. When this occurs, it means the starter is not engaging with the flywheel. This is a worrying situation which could result in having to replace the whole component.
Usually when the starter does not engage fully it is because of a low voltage usually caused by a low battery or bad connections. take the plugs out and you should be able to EASILY turn it over by hand in both directions.

Mower won’t start
ANSWER : This may sound stupid but don’t mean it to…
Have you tried with the choke all the way open? Do you have an automatic cruise? Is the right (correct) pedal being pushed in? These will affect if it starts or not. Also if your drive belt or one of the other belts not being tight enough will affect if it starts or just turns over. Not too many things can stope it from starting with new/good battery AND if its getting gas. Try cleaning your gas line and obviously making sure there is no obstruction around or near your blade, if it does start with blade engaged that is :))
If it doesn’t start with blade engaged, well make sure it’s in neutral. Mine won’t start in reverse but will in forward or neutral.

Hope it helps.
