Not used for 6 mos. (ran well at last use). Starts, runs 5 sec at idle or 2 sec at speed, then dies. Repeated this three times. I assume spark good, fuel problem of some kind. Any offers on priority of things to try? thanks!!
Experienced gardeners share their insights in answering this question :
Most likely fuel “Air” problem.Old fuel can and will gunk up the air flow jets.Would suggest cleaning the carb and filters.Then replace with good fuel mixture and start again. :)Make sure the choke is set correctly and the air filters are clean.Had a lawn mower that would NEVER crank correctly after sitting idle for the winter. Had to dis-assembly the carb and clean literally with paper clip and tooth brush. Never once had to change the spark plug or wires. After spring cleaning (LOL) it would usually crank on the 2nd pull.Good luck!

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 :

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 reason for that may be you`re using the saw at altitude or the carburetor adjustment has simply slipped. The saw also won`t operate well at speed if the air filter or spark arrestor or carburetor are dirty.
How long the chainsaw runs before dying depends on how badly clogged the air filter is. In the case that your chainsaw runs for a while, then dies, it may be possible to simply clean the air filter to correct this symptom. However, a damaged air filter should be replaced.
If your chainsaw still starts and then stops working, check the air filter. Clean or replace the air filter if it is dirty or damaged. Another reason that your chainsaw starts and then stops working could be that the spark arrestor is dirty or clogged. If this is the case, clean it with a wire brush.
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 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 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.
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.
Information we found online suggests that Stihl Pro Chainsaws have a run time of about 2,000 hours. That means the saw would last you for a minimum of 5.5 years before dying. Keep in mind this time is rated for professional chainsaws and not for regular homeowner saws.
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.

Stalls under load nearly new chainsaw ran great last fall this spring stalls under load starts and runs fine otherwise
ANSWER : Try opening up the high speed jet, see if it does any better. Turn it just a quarter turn at a time, if opening it up doesn’t do anything, try closing it. If that doesn’t do it, try closing it down all the way, then open it up 1 1/2 turns, this will put you into run mode, you can adjust it from there. You have 2 screws on the side of the carb, low, high, they are marked, don’t be afraid to turn, that is what they are for. Check it out.

ANSWER : I am not familiar with where the adjustment screws are for this but is sounds like you need to adjust the high end of the carb. There are two small screws and you can adjust these while the machine is running. Dont over turn these, it only takes a very small adjustment and always make a mental note of where you were originally.

Trouble with all three of my old Poulan Chainsaws. After starting and attempting to cut, chains either keep getting loose or very tight and stalls chainsaw. Would you think bent bar or dull chains? Thanks…Chuck

You can have chains sharpened.
Just because you added oil does not mean it is getting to the bar. Your manual shoul explain how to test.
Chain Adjustment

Make sure the chain brake is off (gloves will protest your fingers).
If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They do not need these really loose – finger tight will do.
Ease the tension adjustment until the chain is obviously loose.
Using one hand, hold the nose of the bar up.
While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system. HTH
