Well....I finally got the carb cleaned out after sourcing the appropriate Welsh plugs and screens. Pulled the cylinder and amazingly....both the cylinder and piston are pristeen. So...got 'er all slammed together with fresh gas and a new plug - *Bingo*!!! Roared to life like it was brand new!! Put it up against my Stihl 460 and my buddy's Husky 372 XP and it wasnt even close. The 133 Super cut a 40" log in half the time of the 460....and even quicker than the Husky. Both the 460 and Husky had lighter sharper chains....with the Dolmar running a new chain out the box(re:heavier!). The only huge drawback was the weight. With both the Dolmar and Stihl running identical 28" bars and skip tooth chains....the Stihl only weighed 20lbs....the Dolmar was hitting 27 pounds as measured!!! Ouch!!!
