This sounds like a sticky throttle cable.Check that it’s route is un-inhibited.Though, the cable itself may be freyed, and thus in need of replacing.Happy and safe chopping:)

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 engine is likely to stall when the filter gets plugged with dirt and dust as too much air is filtered which deprives the engine of adequate air which is necessary for combustion. The air filter on a chainsaw is located at the rear. Loosen the fasteners and remove the filter to inspect for any dirt.
The two most common reasons a chainsaw won`t idle are a blocked air filter and an idle screw out of adjustment. Other possible causes include: Dirty Air Filter. Idle Screw out of Adjustment.
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.
Chainsaw Chain Keeps Moving at Idle – FIX A – Faulty Clutch

Either replace you clutch, clutch spring, or tighten the spring. There could be lots of sawdust or wood chips stuck in the clutch, if so get rid of this.

Dirty Carburetor (air+fuel)

If fuel sits in the system for too long, the carburetor (and the engine and fuel lines) can become sticky and clog. Remove the air filter and spray the carburetor with carb cleaner—an aerosolized acetone spray made to remove the gunk.

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.
If the filter becomes clogged, not enough fuel will reach the engine for it to run properly. Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle.
Worn/slipping clutch

A slipping clutch will cause the engine to rev higher as the transmission struggles to work correctly. If your clutch is slipping, the clutch pedal will take much less pressure to engage. A slipping clutch will also cause your vehicle to lose power and struggle to stay up to speed.

If the RPMs are too high, try dropping it down a gear. This can solve the problem quickly and easily. Depending on what equipment the engine is hooked up to, you may be able to control the RPMs with gears. If the RPMs are too high, try dropping it down a gear.
If the mixture of oil to fuel is too rich, too much oil is in the fuel and it leads to the engine losing power and dying. Open the fuel cap and pour the old fuel out of the tank into a disposable container. Mix new fuel in a gas can with a ratio of 50 to 1.
1. Dull chain and or improper lubrication to the bar and chain, sharpen and or clean the bars oil holes. 2. Air filter and fuel filter for restrictions and contamination, clean or replace as needed.

Husqvarna Model 136 chainsaw will only run for a short time with choke closed. Engine quits shortly after choke is opened.
ANSWER : Take apart the fueling system and carb. Something is blocking or gummed up. One thing that sometimes works is to remove air filter, rev the unit up, and place hand fully over the intake, and remove before unit stalls. This sometimes will clear the blockage.

Hi there,

I got the Husky 240e, with only ~4h of running. my problem is that the chainsaw starts smoothly but when pressing the throttle it is suffocates and turned off. When gently squeezing the throttle it generates speed but once the throttle further squeezed it choke.
I checked the air filter which is clean and the clutch (the chain is free running).

The chainsaw stand in the garage for about 4 months and worked perfectly before.

Can you figure out what happen here? is it fuel filter that might blocked?

Thank You

ANSWER : The symptoms indicate lean running, so check the fuel filter for plugging and the fuel lines for decay or other damage. Husky seems be having troubles with our ethanol treated fuel and may require some warranty attention. We have a year old 435 Husky that would not start after about 3 days of excellent running–warranty replaced the carburetor which seems to have us working well now. Good luck!

Husqvarna 345e Hard to start and when it does start it continues to run (chain).
ANSWER : I have a model 435 Husky that had the same hard-to-start problem–warranty service replaced the carburetor and it seems to work ok now. The chain that continues to turn can be fixed by turning the idle-speed screw (not the H or L jet screws) CCW a small amount until it can be accelerated then dropped back to idle to quit driving the chain. Hope this helps!

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.
