Chainsaw Repair

JMO I would do the  FULL THROTTLE in wood 3-5mins per owners manual. Just keep making cuts with bar buried if you can and see.

straight from owners manual = The following steps should be taken when the chain saw
is started for the first time or when outside circumstances
change (fuel, altitude, air filter etc.): Start the engine.
Accelerate the engine to full throttle and saw a number of
cuts in a thick log (3-5 min.).
The chain saw must be run (8,000 - 12,000 rpm) the entire
time so that the carburettor can adjust itself. ------- 8K to 12K must be kept up in rpm in the cuts.

Oh when I got it home from the dealer it was smelling up the shop with gas smell no leak to be found... What is the deal with the newer muffler for flow better?

Cant just buy them. Thats the BS of it all.

Just so your aware. Just in case. Go run it like mentioned above 3-5mins in cuts wot

To make those 3-5 minutes cuts at WOT,  it's best to stand a log round on end and make long rip cuts side by side down through it rather then cut cookies.

My new 2016 550XP manual np longer recommends the 3 to 5 minute WOT....just run it until it runs good

Spike 60 informed me to get my Husqvarna dealer to update his tech bulletins with the latest codes to reset the fuel settings.
Can't remember the code#. I'm away on holidays at the moment.
