Runs great for 30 sec. to 1 min. then dies slowly

when ??? dies at wide open throttle ??? dies at idle ??? dies it restart right away or take an hour or more ??? did you put the right 2 cycle mix in the gas tank ???

If it will run for ten minutes before it stops i would say it is either the fuel tank breather ( to test this slacken off the fuel filler cao when it starts to die, if it picks up again replace the breather ) or it is a problem with the ignition unit breaking down, replace the ignition unit.

Remove the fuel cap to see if the saw will run longer--if so, the fuel vent would appear to be plugged. If no help, then check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. Hope some of this helps!

With saw running and high speed hold saw close to a piece of wood and check for oiling. If still no oil, then use air pressure at hole in bar to clear.

Take the saw back for warranty service. We have a Husky #435 that had starting problems when new last year--warranty service replaced the ignition module the first trip, then a little later, they replaced the carburetor--it has worked very well since. I suspect that Husqvarna has had problems with our ethanol blended fuels. Hope this helps!

Check the fuel lines for hardness, cracking, splitting, or end rot. Check the muffler for plugging. Check the carburetor fasteners for tightness. Are you using fresh fuel mix? If the carburetor jets have been adjusted, try turning both CW to stops (lightly) then back out each CCW 1-1/2 turns. Engine should start and run--allow to warm up. Pull the throttle full on, and adjust H needle CW until the engine starts to speed up, but still 4-strokes. Proper adjustment is when the engine 4-strokes, but immediately 2-strokes when cutting. Let idle and adjust L CW for fairly smooth running, but still allows the engine to 'follow the throttle'. Hope this helps!

Hi Dave:
If you hold the bar nose up when adjusting and tightening the bar, then I think your saw is like detail A here (may not be your saw):
http://weborder.husqvarna.com/order_static/doc/HIUS/HIUS2008/HIUS2008_506955901.pdf
Configure it like detail B and the problem is solved. I did a quick search for item 16 (<$25) and available. You also need item 14 (2 each, $1±), and a scrench ($10± at a local saw store after you get the bar nuts).

If the saw listed is not yours, you can find yours here:

On the bottom of a hose in the fuel tank. Did you replace or disconnect the fuel lines? I think improperly plumbed. It should be similar to this.

check crankshaft seals,maybe sucking air. most of the time the seal on the starter side. hope this helps.

I have a nearly worn out 42 cc Husquvarna that uses a 20 inch bar very successfully. With proper filing of the chain you should be able to run a 22 inch bar very well. Ensure that the roller nose on your new bar matches the pitch of the clutch sprocket that you are using at present. If not, have your chain saw shop change them so they match.

I would advise that you change the bar and sprocket to use a .375 chain as this will be easier to sharpen successfully than the .325 pitch chain you might be presently using.

I am six feet tall and short bars are murder on my back so this is why I use no shorter than 20 inch bars on my saws.
