I have a push lawn mower that is idling high and low. It is a briggs and stratton with a rectangular tank and carb on the same side. I have check the governor spring which seems fine. I have also taken off the fuel filter and cleaned it. It still idels funny whether your stopped or pushing it. Any ideas?
Experienced gardeners share their insights in answering this question :
I don’t know what type carb is on this one, but most have a diaphram. If the diaphram is weak it will cause this. You can purchase a new diaphram at a Lawnmower service center. It’s not that hard to install.

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 :

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.
Lawn mower surging is a result of either bad gas or spark plug, dirty air filter, or clogged gas cap vent. A dirty carburetor jet and fuel filter might also be the reason. You can also consider a carburetor gasket leak, which can be fixed by an engine starter spray.
Troubleshooting a lawn mower that is surging

Check the air vent on the fuel tank cap. Clear the vent hole if it`s clogged. Replace or clean the air filter if it`s dirty.

If the spring is set in the wrong position it can cause the engine RPMs to surge. Over time the spring can stretch out, causing the same engine surging. Often surging caused by the governor can be fixed by simply adjusting the governor spring. It usually only takes a small adjustment to correct the surging.
The most common problem is a faulty fuse. In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. This can be impacted by bad fuses in many different electronic systems in your car. Next, your high idling could be caused by a computer malfunction.
Possible Causes of High Idle Speed

The engine may be overheating, and the cooling system might need repair. The fuel pressure regulator may be operating at too low of a pressure and might need to be replaced. The Ignition timing might be in need of adjusting.

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.

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 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!!!
