The governor does not increase engine speed when it has a load put on it and the engine stalls. This all started after the engine shut down and I could not start it. I then tried to re-set the speed and idle like I have on a Biggis & Stratton engine.

I still could not start it and took ff the air cleaner off and found that the throttle cable had broken and replaced that. The engine has never run right since. My attempts at adjusting the engine have failed.

Help!

Hi

first check the governor linkage.The link with the governor sistem from crankcase is the lever(arm) with some holes.To encrease the sensitivity, raise the spring into the next higher hole in the arm.To descrease the sensitivity,hook the spring into a hole lower than its original position.If you need more info just tell me.

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.
If the engine will idle but dies at full throttle the main jet in the carburetor may be plugged. You can repair a plugged main jet by cleaning it, replacing the jet, or replacing the carburetor. If you choose to clean or replace the main jet, you will also want to clean the rest of the carburetor.
The fault could be a dirty spark plug, air filter or carburetor, or it could be related to the quality of the gasoline used. Slow starting can also be the result of a failure to clean the blades. In most cases, you should be able to restore performance yourself.
An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.
The governor system is like a cruise control system. It maintains the speed of your lawn mower or outdoor power products.
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 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.
Why would the engine only run while the choke is on or with repeated manual priming? An engine that requires the choking (partial or full) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment.
A lawn mower that only runs with the choke on might be having problems with the carburetor, air supply, or bad fuel. Maintaining a clean carburetor will make the fuel delivery system run smoothly. Use high-quality fuel to extend the lawn mower`s life.
The lawnmower governor is designed to maintain the engine speed set by the throttle lever, regardless of the load imposed. When the engine slows down while cutting through thick grass, the governor opens the throttle automatically, thus maintaining the preset engine speed.
The acceptable operating speed range is 1800 to 3600 RPM. Idle speed is 1750 RPM. The manufacturer of the equipment on which the engine is used, specifies the top governed no load speed at which the engine may be operated. DO NOT EXCEED this speed.
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.

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.

Use carburetor cleaner to remove deposits, clogs & debris

Deposits inside the carburetor can clog fuel and air passages and reduce performance or stop the engine altogether. Luckily, you can take care of many of these problems quickly and easily; often without even removing the carburetor from the engine.

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.

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.

If the engine starts, but does not run smoothly, it means that the spark plug and ignition system are in order and you need to look elsewhere for the source of the problem. The usual culprit is air intake or fuel system related.
A stuttering mower could be caused by a variety of factors, including old fuel, dirty air filter, or a faulty spark plug. Try cleaning or replacing these components. There are a number of causes for a lawn mower to lose power when cutting that you can easily solve yourself.

I have mtd large wheel push mower tecumseh model 501039c engine has no spark to plug, coil checks good. i have disconnected the ground wire from the coil that leads to? and grounded the coil to another part of the mower and will get spark to the plug that way. I have not tried running the mower with the coil grounded where I have it. What can be the problem?
ANSWER : I would say if you can get a spark by moving the ground, try running the mower. If it works you should be OK.

Runs fine on flat ground will not pull a hill
ANSWER : Sounds like you could be running on one cylinder. I assume you have a two cylinder B&S, Tecumseh, or Kawasaki. Remove one spark plug at a time and try driving the mower. If you have nothing on one spark plug and drives exactly the same with the other, then you have a dead cylinder. Can be a spark problem, unlikely a fuel problem assuming a single carb, a bad head gasket, bent push rods. A lot of B&S Vanguard engines, including mine, have a tendency towards bent push rods.
