I have the exact model except I think it's the "easy start" model. LOVE it...been using it daily without anything but gas for 7 years now. No tune up, no plug, nada! And for $139 bucks...if it broke, I'd just buy a new one and toss the old one.
I also have the Mac Daddy STIHL... it blows so hard, I can barely walk when it's blowing me
