Mower is getting fire and fuel but will not start
Experienced gardeners share their insights in answering this question :
My Stanley was running fine and died one day with no luck. I checked everything, well, so I thought. After setting for a year my uncle and I pulled off the gas tank and found the fuse beside the solenoid was bad. Replaced that and boom with a jump off mower fired up and ran until head gasket blew lol.
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.
If your lawn mower turns over (or cranks) but won`t start, it could result from an issue with one of the components of the fuel system or bad gas. You should inspect the fuel filter for clogs or damage and check the fuel line for kinks, cracks, or leaks.
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.
If your Briggs & Stratton engine has a spark but won`t run, then it is most likely a problem with the gas or air intake in the engine. The spark on the spark plug ignites the gas in the piston, but if the air filter is clogged or the gas can`t flow, then the engine won`t start.
A faulty or dirty spark plug could be the reason your lawn mower won`t stay running. It might produce the initial spark, but the spark won`t be enough to keep the engine running if the plug is clogged with dirt and oil. Spark plugs are usually located on the front of a push lawn mower and connected to a black cable.
Use Carburetor Cleaner
Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced. If the starter motor does not run, the motor itself is probably defective.
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.
Coolant leak: Excessive white smoke coming out from your exhaust on startup suggests that coolant has leaked from the cooling system into the combustion chamber and mixed in with the engine oil. As the combination of coolant and engine oil burns, it consistently creates thick smoke.
If your riding lawn mower engine clicks when you turn the key but won`t turn over, there`s a pretty good chance your mower could have a bad starter solenoid. Other problems, though not as frequent, include a bad starter motor, a wiring failure, a weak battery or a locked-up engine.

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!!!

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.
Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.

I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks

Mower starts and immediately shuts off and wont start again if i let it sit for five minutes it does the same thing checked oil and air filter carb is clean attempting to find correct socket to remove plug
ANSWER : Pull the fuel line from the carb & see if it is running steady, If so the next check is the carb bowl to see if maybe the float needle is partly plugged, and then it could be the valve lash clearance which will require more mechanical knowledge.
