I'm sorry if this has been covered a bunch of times before. I was using my one remaining 200T a couple of weeks ago and it went weak all of a sudden then wouldn't run at all unless I choked it. I replaced the carb on it not too long ago. My cousin took it to the Stihl dealer and the piston is scored. I'm thinking about attempting to rebuild this as I have time now and my question is: What is the best rebuild kit for this saw? I'm assuming there is a kit from Stihl but I thought I would ask anyway. I haven't seen it yet as I am in Victoria, BC for a few more days and my saw is probably a bunch of parts in a box in Patterson, CA.
