I have a T540XP I could part with for the right price. I don't use it enough to have a real need for it. It has less than 15 hours on it over the course of 1.5 years that I've owned it, an actual hour reading can be given upon request. It's got a muffler mod and pulls a 14" bar very well. My local Husqvarna dealer altered the tank vent as per warranty notice put out by husqvarna last year, and they updated the autotune as well. The work was done about 2 months ago. The saw has never run on anything other than 94 Octane ethanol free fuel, mixed at 40:1 with Amsoil Dominator 2 stroke oil and Lucas Oil Fuel Stabilizer. I would take a pic of the piston and cylinder for you but I don't want to take apart the ENTIRE saw just to get the muffler off . The muffler mod was a big job... I'll post some pics of the saw as it is today and I'll post a Cold start video filmed today as well.
Given the fact that the saw is essentially new, I couldn't let it go for less than $700 Canadian + shipping. I paid nearly $900 for it brand new.
