Olympic Piss-reving wanna be.
Wanting to take care of my saw, I let it warm up and left the brake on as Stihl suggests for safety reasons.
Might want to re-read that part of the manual. Pretty sure it says to immediately release chain brake. Your resultant smoky meltdown being the why. As others have said, once they fix the rest, chain brake should be the easy part of the repair.
And where, I say WHERE do so many people get the idea to break in a new saw (or any other 2-stroke) by letting it idle?
Hope your dealer takes sympathy on you and helps you out.
