The black lever above the saw handle is the trigger lock. It must not be possible to operate the trigger unless the trigger lock is pressed down. This prevents the throttle being opened when undergrowth or other obstructions catch on the trigger.
Clogged Fuel Filter

This means the flow of fuel to the engine is disrupted which can then cause the engine to stall. Remove the chainsaws fuel cap and pour some gasoline into a different container when inspecting the fuel filter. Filter the tank by using a thin metal rod and examine the quality of the filter.

The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
STIHL recommends that you do not run your engine at wide open throttle without a load. A blower is under a load at all times, a trimmer is under a load as long as the trimmer head is in place and the line is to the correct length, while a chainsaw is under a load when the bar and chain are in a cut.
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.
Accelerator Pedal Release Position Learning Procedure.

Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds.

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.

How do I replace the trigger on the Huskie 350? Does it just snap out, is there a pin to drive out or do I have to separate the case. If I have to separate the case, how?
ANSWER : To remove the the trigger there is a alloy pin that needs be be driven out. Before you can take the trigger out, you need to remove the trigger lock ( dead man ) to remove the trigger lock, gently pry the two halfs of the tank apart at the rear opening where the lock sits, this will allow the back end of the throttle lock to pop up, once up pull the throttle lock toward the rear of the saw and it will come away ( bayonet fitting in the tank ) the trigger will now come out with its spring once the pin is removed.

Have a Husqvarna 41 about 10 years old. Takes a lot of pulling to get it going but once running it woks allright. Lately it will not start and after new gas and plug it starts but when I engage the trigger to start cutting it totally cuts out and I have to pull it many times to get it going again And when I pull on trigger it dies after 20 seconds. Any ideas on what the problem is?
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note:Before you disassemble the carburetor:Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of chainsaws.When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.Make sure you are using fresh fuel…and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.If the chainsaw is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.Note:The little spring inside of the carburetor goes under the float arm.That is where your fuel inlet needle/float valve is located…on the arm at the end.Normally there is a small indetion in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.Once you have your carburetor cleaned/rebuilt that should solve your problem.Please take time to rate me
