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 :

Clogged or Dirty Air Filters

It is one of the most common problems that cause lawnmowers to sputter. The mowers take the air from the surrounding through air filters and mix it with fuel inside the engine. So, if the air filter is clogged or dirty, it will affect the flow of air into the carburetor.

Water in the Fuel Tank or Fuel Line

If there is water in your tank, siphon or drain it, then add new gas. After old gas in the line works its way through the mower`s engine it should stop sputtering and run like new again.

A dirty air filter inhibits the flow of air into the carburetor. Clean or replace the air filter to stop the mower from sputtering to a halt. Too much air can also cause problems for the engine. A bad cap on the gas tank is the first place to look.
If the fuel amount is too much or too little, the engine may begin to sputter. Your mass airflow sensor tells you how much air is in the engine. Just like the oxygen sensor, the engine will sputter if there is too much or too little air. Spark plugs are an integral part of your engine.
A strip of uncut grass left in the middle of mowing rows could signal that your lawnmower`s blades are unbalanced or that one or both of them was installed the wrong way. Lawnmower blades are beveled and specifically designed to attach in a certain fashion.
Dirty or bad spark plugs won`t cleanly ignite the fuel causing the vehicle to misfire or sputter. You`ll either need to replace or have them cleaned. Because engine sputtering is a symptom of something more serious, it`s important to rely on an experienced mechanic to diagnose and repair the problem.

Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
