chainsaw won't start

What do I have to do to get this Husqvarna 350 to start? I replaced the spark plug, air filter, and fuel filter. I used the correct ratio of oil and fresh gas. What else can I do? I read the manual and followed the carburator adjustment steps. This chainsaw never really starts on the third pull from it was brand new. It's getting harder and harder and now it refused to start. Once in a while I can heard a slight "pop" sound when I attempt to start. That can't be normal. I even took it to the Husqvarna Dealer and they told me it was a bad spark plug. Still it was hard to start but it did eventually started. Now it doesn't start again. Any suggestions would be great before I pull my shoulders out from pulling so much.

How old? Any previous preventative maintenence? What ratio and what brand oil? Do you have spark at the spark plug? Some guesses on my part without much to go on are either a plugged exhaust and/or a dirty/varnished carburetor. The exhaust can be taken care without any parts but the carburetor would need parts and a knowledgeable person to service such.

Only 2 years old and ran for about 2 cords of wood. I used Husqvarna oil that are premeasured for 1 gallon of gas. Spark plug has sparks. I did used carburator cleaner to remove varnished. Exhaust and muffler are cleared.

Provided the piston and cylinder are in good condition, I'd say the carburetor is in need of reconditioning. Honestly, I'd find another saw shop than the one you've used in the past and have them recon the carb. If you don't want to tackle the job, that is. The first order of business, however, is to have a look at the piston and cylinder by removing the muffler and having a peak at such through the exhaust port. Pay close attention for any scoring/scuffing on the piston face as well as the cylinder bore, especially near each transfer port. Also, be sure the ring(s) are free in their landings by simply applying slight pressure with a small blade screwdriver and pressing inward in the landing.

Air leak

I had a used leaf blower with the same problem. It took several pulls to start it and this had gotten continually worse. Finally in disgust I pulled the carburator off only to find one holding screw had been broken in the head and was replaced by the wrong screw. The screw was getting loose and allowing air to leak throgh the carburator gasket. This would not allow the engine to draw in enough fuel to start it. Once started the engine vacumm and heat would try to seal the gap and the engine would run. Check for a loose carburator hold down screw or a broken carburator gasket.
