30.1CC Chainsaw With a 14 In.bar and Chain

The chain clutch won’t release. Even when I am trying to start the saw the chain moves.
I have a cs3000 14 inch saw about 10 years old.
It just started doing this for no reason.
I did try to adjust the idle screw but when I turn it down enough to make the chain stop the engine stops. Thanks
Experienced gardeners share their insights in answering this question :
First; Take the Spark Plug for this Chainsaw and Go to
the Hardware Store or Automotive Parts Supplier and Purchase a Bolt
that is of the Same Diameter and Threads as the Spark Plug. Make Sure
it is 3 to 4 Inches Long. Thread this Bolt Into the Spark Plug Hole and
Carefully Tighten Until the Piston is Blocked and Will Not Move while
you are Loosening the Chain Clutch. You Turn the Clutch Clockwise
(Usually) to Loosen. Some Saws Use a Reverse Rotation; so Remember to
Turn the Clutch Assembly the Same Direction that the Clutch Turns
During Normal Operation. IE: If the Clutch Turns Clockwise, then the
Clutch is Loosened and Removed by Turning it Clockwise and if the
Engine Rotation is Counter Clockwise, the Clutch Assembly is Turned
Counter Clockwise to Remove. Being Sure the Piston is Solid Against the
Bolt in the Spark Plug Hole and Use a Shop Maul (a Regular Hammer May
Work Also)and Chisel (Wear Safety Glasses also to Protect your Eyes)
and Hit the Clutch Ear Sharply so as to Turn the Clutch Assembly and
Loosen it. Heat is Not Required and Not Suggested. If you Use Heat to
Remove the Clutch Assembly, then Replace the Clutch Assembly and the
Sprocket. The Clutch Assembly is No Good After Heat is Applied to it.Thank you for using FixYa! Please Rate!

Carburetor Idle Adjustment

The most probable – and easiest to fix – cause of chain rotation while the chainsaw engine idles is a poorly adjusted idle setting on the carburetor. The result is that too much fuel is delivered to the combustion chamber when the throttle is released, and the engine doesn`t really slow.

There are many factors that can stop your chainsaw from running, including a bad spark plug or dirty air filter. There are simple problems: a broken fuel line, bad fuel, wrongly calibrated high-low adjustment screw. Also, more complex issues like a damaged carburettor or an engine compression problem.
The carburetor regulates the ratio of air and fuel that enters the engine. If extra air enters the mixture after the carburetor, the ratio will become lean, which will increase the engine RPMs. This air can enter through the gasket on the carburetor if the gasket it loose or damaged.
If the carburetor is clogged, it may only work with the choke engaged, which is not a good way to be running your engine. Cleaning the carburetor and replacing some of the internal parts with a new carb kit is a great way to get your carburetor running properly again.
My chain saw starts and then dies what is wrong? This could be a number of things and is most likely fuel or storage related. Over a short period of time, fuel will become stale. If the unit is stored with stale gasoline, the system will become clogged or restricted.
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall.
This can be caused by a variety of things, including low transmission fluid levels, worn-out clutch pads, or a problem with the torque converter. Another possible cause of over revving is an issue with the engine itself. This could be something as simple as a dirty air filter or spark plugs that need to be replaced.
There could be various causes: incorrect fuel mixture, carburation not calibrated properly, or a wet spark plug. In spite of their power and robustness, chainsaws are actually rather delicate machines that require careful and precise maintenance at every stage of their life cycle.
Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised. Cutting a thick wood or timber while running at a low speed or throttle can cause the blades of the chainsaw to become dull.
The idle air control valve enables the engine to idle smoothly rather than stall out while the vehicle is stopped. It will continue doing so until you step on the accelerator and the vehicle starts to move again. In gasoline engines, engine speed depends on airflow, which is controlled by the throttle body.
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.
An engine stalls when it`s getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw stalls while it`s idling, adjusting the idle screw, which usually is marked LA, should help.
If the springs are broken, the clutch pads won`t retract, preventing the chain from stopping. If the clutch pads are sticking, the clutch drum will stay engaged and continue to turn. If the springs are broken or the clutch pads are sticking, replace the clutch assembly.
Restricted Fuel Lines

The engine can be suffocated from gasoline when at peak demand for fuel if there is any slight restriction or debris in the fuel lines. The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle.

I have a new Husqvarna chain saw and when it is turn on its side it dies whats wrong.
ANSWER : Its hard to say what is causeing this, there will always be a slight difference in rpm as it moves from side to side, the fuel hose should move in the tank and follow the fuel, if the machine is idling to low it may stop as you turn it, make sure the fuel hose is not trapped in the tank.

Craftsman 28cc 16" chainsaw wont idle – Craftsman 38cc 16" Gas Chain Saw
ANSWER : If you’ve already tried the idle adjustment screw and that didn’t work, you need to turn the low side adjustment CCW a quarter turn and try again.

I have a Poulon chainsaw problem. I bought it of a “E-bay” type site. Have replaced the starter cord, put a new fuel line in, replaced the fuel filter and serviced the carb. I’ve adjusted the H and L screws as best i could, but the idling seems to fluctuate. Goes from idling too fast too just dying. Also when i got it to run for a little while and started to use it, the chain would go tight on the bar obviously adding extra drag on the motor, causing it to stop…., can you please help ?
ANSWER : Buy a husky

When I disengage my chain brake to stop the chain it shuts the chain saw off rather than let it idle until I need to engage the chain again.
ANSWER : This is probably an issue with either the clutch spring, or the sprocket bearing, if there is any drag from either of the components it will drag the engine down to a stop when the brake is applied, check the clutc spring if you can pull the shoes out by hand the spring has streched and will require replacment, turn the sprocket around manually, if there is any resistense ( drag on the crank ) then grease the sprocket bearing.

Makita DCS6401 wont idle. When the gas is released the chainsaw shuts off.
ANSWER : Try turning the idle speed screw CW (not the jet screw marked L) one full turn to increase speed. Normally, this is set so that the chain stops moving, but the engine continues to run. Hope this helps!

Chain saw chain is loose
ANSWER : Loosen the side cover nuts, then turn the adjuster CW to bring the chain up to the lower edge of the bar, then check to see if the chain will move fairly easily by hand. Tighten the clamp nuts and recheck tension. If chain seems to get loose quickly again, it may not be sharpened correctly causing heat to build in the chain. You should see no reflection of light from the cutting edges if filed correctly and the saw should require very little pressure for it to cut rapidly. Hope this helps!

Mower won’t start
ANSWER : This may sound stupid but don’t mean it to…
Have you tried with the choke all the way open? Do you have an automatic cruise? Is the right (correct) pedal being pushed in? These will affect if it starts or not. Also if your drive belt or one of the other belts not being tight enough will affect if it starts or just turns over. Not too many things can stope it from starting with new/good battery AND if its getting gas. Try cleaning your gas line and obviously making sure there is no obstruction around or near your blade, if it does start with blade engaged that is :))
If it doesn’t start with blade engaged, well make sure it’s in neutral. Mine won’t start in reverse but will in forward or neutral.

Hope it helps.

My chain rotates on idle when tension is ok. How do I adjust clutch drum to stop this happening ?
ANSWER : The clutch drum is probably ok, just turn the idle adjustment screw CCW to reduce idle speed (not the jet screws). If you turn it too far, the engine will stall.
