Chain saws are 2 cycle engines that like to work at high speed, and they are not known for a smooth idle.
Make sure the gas filter and air filter are clean, and that the spark plug is good. There are idle and mixture controls on the carb.
Keep it well maintained and run fresh gas with the recommended oil mix and you should get years of service from it.

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 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.
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.
If your riding mower`s e engine runs rough or misfires, the carburetor could be clogged.. Rebuild or replace the carburetor if it`s clogged. If the engine runs rough after hitting a rock or stump, check the flywheel key-a damaged flywheel key will disrupt the ignition timing.
If the idle is rough, your vehicle is struggling to maintain a steady rate of rotation. This could be caused by a number of different problems, including dirty fuel injectors, clogged air filters, bad spark plugs, or exhaust system problems. A car that stalls can be extremely dangerous while on the road.
The main reasons for an Engine Surge at Low RPM are Air, Fuel, Spark, and Compression which can be detected by the below indicators: Dirty or faulty mass airflow sensor. Clogged or dirty fuel injectors. Faulty spark plugs or ignition coils.
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 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.
Incorrect amounts of air or fuel will cause the engine to run sporadically or not at all, as will a weak or improperly timed spark. An engine not getting the right amount of fuel, air or a proper spark will exhibit a loss of power.
Engine Misfires
Perhaps the single most common cause of rough idle comes in the form of a misfiring engine. As you may know, any automotive engine contains multiple cylinders. Each of these cylinders contributes to powering your car by combusting a mixture of gasoline and air.
While it may seem like a small problem on its own, rough idling is a sign that some part of your engine isn`t working properly. Over time, rough idling can result in poor gas mileage, starting issues and major engine problems.
A weak accelerator pump, worn throttle shafts, or dirt inside the carburetor are a few of the problems that might be causing the poor air/fuel mixture. Another recognizable sign of carburetor trouble is rough idling .
Cleaning out the carburetor to remove carbon deposits is probably a good place to start. Then you should check all the vacuum hoses – a leaking hose can cause a too-lean mixture and a rough idle. Other places to check in older vehicles are the distributor cap and rotor in the ignition system.
Along with faulty spark plugs, a build-up of dirt and grime is the likely cause of cars stuttering when idle. A clogged filter or fuel injection system can starve your engine of fuel or oxygen, causing your car to judder and shake.
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.
Dirty air filters are one of the most common reasons lawn mowers sputter. Dirt can be present in the apertures that lead from the carburetor and the fuel filter and interrupt the flow of fuel supply to the combustion chamber. You want to be sure to clean or replace dirty air filters.
Replace dirty or clogged fuel filter. Replace old gas with fresh gas (properly dispose of old gas). Check oil level and add if low. Adjust cutting height of mower before cutting tall grass.

Idle goes up and down and the shuts off eventually
ANSWER : It sounds like the engine might be running too lean. You need to get someone to adjust the idle and high speed screws correctly.

MY PUMP WILL ONLY RUN ON LOW SPEED ( NEUTRAL AND BLACK) . PUMP IS MARKED 230 v , ? DOES THIS RUN ON NEUTRAL TO 120 FOR LOW SPEED AND NEUTRAL TO 120 FOR HIGH SPEED AND USE SEPERATE WINDINGS OR IS HIGH SPEED CONNECTED ACROSS BLACK AND RED. (230v)
ANSWER : If this is 220v then your netural is not a netural but a common. Meaning it is common 110v to both the high and low speeds of pump. The high and low speed are the same leg of the 220v or the other 110v leg they just separate at the clock or high/ low switch. Then yes they run through separate windings for high and low.
If your not getting high speed it could be the high speed winding but be sure to check your switch and high speed lead first before doing anything else.

The engine idles way too fast and will not correct with the sow speed adjustment
ANSWER : Make sure that you are adjusting the idle speed screw, not the idle jet screw (L). If you are adjusting the proper screw, then it is possible that the throttle trigger assembly in the handle has a load of sawdust/dirt that blocks proper return to idle. Take the handle apart carefully, and make notes on how the parts go back together. Check at the carburetor throttle assembly to make sure the throttle arm returns fully to the idle speed screw when the trigger is pulled and released slowly. Check the throttle spring as well to make sure it is undamaged. Hope this helps!

Runs slow at full throttle runs slower than mid-throttle. Won’t deliver full power.
ANSWER : In California the new blowers have sealed mixture adjustments and you need the have your carb. mixture adjusted be a qualified shop. If your carb. HAS mixture adj., turn the high speed mixture so it runs best at high speed, then turn another 1/8 turn counter clockwise to be a little rich. Then at idle adj. the other screw till it idles best.

When I start the motor it runs on high idle and the blade starts to spin without hitting the trigger… When I hit the trigger it sputters and turns off…
ANSWER : I don’t know if your saw has adjustable needles on the carb, but if it does, the “low” side needle needs to be turned counterclockwise about 1/8 to 1/4 turn. THis will richen up the idle mixture which will take care of the sputtering, and should also bring down the idle speed.

What causes your saw to run hot and not idle it wont run unless you hold the trigger and wnen you let off it dies i have new fuel ines on it have cleaned the carburator
ANSWER : I’m assuming you are using the correct fuel/oil mixture. Your carburetor could still be clogged or misadjusted. The symptoms you describe are those of an air cooled engine running too lean. Also you might want to check the exhaust port to make sure it isn’t clogged with carbon.

Will only start and run in choked position, when throttle applied chokes out. If started with out choke and throttle position in low speed will start and run for 10 sec then like it runs out of gas.
