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 :
If the plug is clean or you`ve replaced it and the mower still won`t start, the issue could be a lack of fuel. Either the carburetor is dirty and not able to mist the fuel to be mixed with incoming air, or no gas is getting to it to begin with.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
An airlock is one of the common causes why your mower won`t start after running out of fuel. An Airlock occurs when air replaces fuel in the fuel lines. As you refill your fuel tank, you could push the air towards your mower`s carburetor, which keeps the new fuel from reaching the engine.
If your carbureted engine turns or cranks but won`t start, there`s not enough fuel or spark. Here`s what could be causing your engine to crank: Bad crankshaft position sensor. Clogged fuel injectors.
Q. Why is my lawn mower turning over but not starting? The most likely reason is bad gas. Gas that sits for many months during the off-season will eventually break down, gumming up the fuel line and carburetor in the engine and preventing it from starting.
Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination. Yet 90% of spark plug damage claims are due to improper torque.

Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
After spraying the carb cleaner, attempt to start the engine. If the engine runs at all, then the issue is with the fuel system. If the engine refuses to start after several tries, however, then the problem may be more serious. In that case, take your mower to a small engine repair shop.
Expired gasoline can damage internal components of your carburetors, deteriorate fuel lines and seals, and cause a varnish build up that could clog small fuel ports which are necessary for your machine to start and run. Fresh gasoline is essential to the proper starting and running of a machine.

Check the Fuel Filter
To start, tap the side of the carburetor to help the flow of gas. If that doesn`t work, you might have a clogged filter. Not all lawn mowers have a fuel filter, but for the ones that do, it`s usually located in the fuel line or the fuel tank.
To manually prime your lawn mower, simply add fuel to the carburetor of the mower when there is no fuel. Some lawn mowers do this process automatically while others do not.
