Lawn Boy Self Propelled CARB Walk Power Mower
Model # 10323, Serial # 200005626 Speed is unstable
Experienced gardeners share their insights in answering this question :
Speed control for motor is controlled by an automatic governor, so there isn’t any adjustments. Surging is caused by an air leak. Has the air filter been changed? Spray card cleaner around that side of the engine to find the air leak. Does it have a choke adjustment? Make and model would be handy in answering this question!
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 :
If your lawnmower`s engine is surging it could be a problem with the carburetor. The carburetor mixes air and fuel to the perfect ratio for combustion. There are passages and nozzles (called jets) that route the fuel through the carburetor. The jets meter the precise amount of fuel that is needed for combustion.
Self-propelled mowers are available in single and variable speed models. They work by engaging a speed control lever (sometimes part of the handle; sometimes a separate bar or shifter) that causes the mower to move forward.
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.
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.
The most common cause of excessive vibration is an unbalanced blade. If you`ve recently had your blade sharpened, it`s possible the blade hasn`t been properly balanced during the sharpening process. To fix this, the blade should be removed, rebalanced and refitted.
The basic function of a variable speed drive (VSD) is to control the flow of energy from the mains to the process. Variable speed drives sit between the electrical supply and the motor. Power from the electrical supply goes into a drive and the drive then regulates the power that is fed to the motor.
Depending on the model, Bad Boy Maverick mowers measure 75 inches in length with an overall width ranging between 54 to 76 inches. On average, these mowers weigh between 862 to 925lbs and attain speeds of up to 9 mph.
When a lawn mower surges, it sounds as if the engine reaches full speed, only to decelerate quickly. Typically, it doesn`t die, but the surging may repeat during the entire time the mower is in use. Like other small engines, mowers rely on a precise volume of gasoline and air for smooth operations.

As a starting point in my shop i always use 0.30 in. For all my mowers
Lawn mower cranck but wont start…
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 had a poulan pro 550 series push mower for almost 1 year at the end of the season last year the mower would start briefly and then stop. i have cleaned out the air filter and that did not help.the mower started, i made one revolution around the yard 3/4th of the way the mower quit. 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
There is a little spring that works the carburetor arm. If that popped off then the mower will not run.

What causes JD 260 riding mower to start dying when you engage the mower deck? It runs fine when you disengage the mower deck.
It’s the safety system that causes this. There is a switch under the seat that should activate when you are sitting in the seat. The switch can come loose or fail, the mounting can break, or the wires can come loose – any of these would cause the “engine dies when I engage the mower deck” behavior. Lift the seat, examine the switch. Rmove the switch and keep the plunger in with a piece of tape. Fixed? Then it’s just the mounting or adjustment. Not fixed? It’s the switch itself or the wires or connectors to it.
