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 :
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
As the fuel level drops, a vacuum begins to form in the fuel tank because air can get in to fill the space the consumed fuel occupied. After about 10 or 15 minutes, the vacuum will become strong enough that fuel will stop flowing to the carburetor and the lawnmower will die.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
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 common cause of a mower that runs for thirty minutes and then dies is a faulty armature. A faulty gas cap is the second most likely cause.
A dirty carburetor is the most common cause of a lawn mower that starts and then dies. Other possible causes include: Stale/Dirty Gas. Faulty Choke.
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.
If your lawnmower will start and run with the choke on but dies when the choke is turned off, it may have a problem with the carburetor. The carburetor brings air and fuel together and mixes them in the perfect ratio for combustion before they enter the engine.
How long is gas good for a lawn mower? Gas lasts in the tank / container around 1 month, if you do not use it at all and keep it inside out the sun and weather it will last about a month but you should always try and store a mower with little fuel in, and add fresh to start it.

Can I replace the blades on my 38in MTD/Yard Machine ride on without removing the deck? ie. from underneath.
ANSWER : If its in good condition you might be able to but be careful so mower doesn’t fall on you. I’ve used my car ramps and backed the mower up the ramp and was able to do it safely. If you have any difficulty removing the blades, then I’d take the deck off. It really isn’t that hard to remove the deck.
