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 :
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.
Electric lawnmowers may cut out for two main reasons: A faulty power switch or a loose cable connection. An overheating motor can cause the thermal cut out to trip.
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.
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.
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.
Another reason a mower might start and then stop is that the air filter becomes blocked. If this is the problem, then it`s good news because it`s easy to fix since most mower filters are cleanable. Check to see if the filter is blocked and clean as necessary – then try again to see if this has solved the problem.
The spark plugs are worn or damaged
If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.
Mower Gas Cap
If the tank is sealed, the fuel becomes air locked, and the mower stalls. This typically happens after a short period between ten and thirty minutes and also depends on factors like weather and gas tank fuel level.
Knowing you can expect your residential lawn mower to last you around 450-500 hours is helpful in the decision-making process. The closer you are to the end of the expected lifespan, the more you should consider replacing it if a large issue occurs.
After you fill the gasoline and top off the oil, if needed, press the primer bulb in firmly and hold it in for a second before releasing it slowly. Press the primer bulb three times to start your lawn mower with a cold engine. If the air temperature is below 55 degrees Fahrenheit, press the bulb in five times.

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!

Can you run your lawn boy mowers without the primer button being used?
ANSWER : Yes you can. The only reason small engines have the primer button/bulb is to get gas to the carburator to make it easier to start it. If your mower starts OK without using the primer bulb you will not harm the mower.
