Blower will start and idle (rough at least)but if I give it gas it stalls out. But it will start up again, do the same. my thought is a plugged fuel filter? Blower is 4 years old.
Experienced gardeners share their insights in answering this question :
More than likely its a tuning issue, needles and jets can get gummed up if the engine has sat round for a while with fuel in it. The fuel tends to evaporate and leave behind the 2 stroke oil residue.
Unscrew both H and L tuning screws (not all the way out, just a few turns) You may need to purchase the tuning screwdriver as Husqvarna blowers are fitted with Walbro carbs that have tooth edged tuning screws. Once you have unwound them a few turns, Pull the blower over (a few times. It may fire up, it may not) Then to reset them to factory settings Screw them both all the way in and then turn them each out anticlockwise 2 & 1/2 turns.If its still not running right it may need more investigation but it definately sounds like a fueling problem.

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 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.
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.
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.
Fuel Filter is Clogged
When it`s clogged, this affects the flow of gasoline to the engine which then causes the engine to stall. The fuel filter will need replacing if it appears to be clogged yet if it seems clean, it may be a different problem causing the engine to cut out.
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.
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.
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. Fuel related failures are not warranty.
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 chainsaw won`t start, or starts and then stops and you find the spark plug wet with fuel mixture, it means that the engine is flooded (you will probably smell petrol). It happens when too much fuel enters the combustion chamber, possibly because you have pressed the primer many times.
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.
Storing regular petrol inside a machine can cause blockages and gumming to the intricate fuel delivery parts, so the most important thing to remember is that whether you`re storing a chainsaw or garden power tool such as a petrol lawn mower you should store your tool without any fuel in it.
Even if your saw is in ideal working order, it will overheat if you overwork it. Two ways to do that are to operate it with a dull chain and try to make it do something for which it isn`t designed, such as cut a curve.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
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.
Fuel: Make sure it is fresh and correctly mixed (see `Starting Issues`). Air filter: Make sure it is clean and unclogged. Fuel cap: Make sure it`s hand-tight. Please ensure when you are attempting to use the chainsaw that the chain brake is disengaged.

The blades are cutting unevenly – Craftsman 17.5 hp 42 in. Deck Lawn Tractor – CA Model
ANSWER : I know this will sound a little crazy, but check the air pressure in you tires. My neighbor had the same problem. The tires looked okay until he sat on the mower. One of the rear tires was low which caused the mower to sit lower on one side. Next check the linkages on the deck to make sure they are hooked up and haven’t fell off.

Cranks up and runs fine ,then starts cutting out then runs fine and starts cutting out again
ANSWER : I am no pro but my suggestion to you is if you have changed your spark plug recently check the gap on it and make sure it is right and make sure is the right spark plug for it. Also check the oil if it is low the motor as it gets hot will start to sputter or if it has to much oil it will have an air lock and blow you Lhead gasket after a while. Another thing to check is the air filter to make sure it is clean and check the timing with this if you don’t trust your self ask an repair expert for your brand of mower.
