I have a 2002 Rancher that runs smooth as silk, idles perfectly, but has lost its midrange and high end power. I used to be able to pull away and accelerate up a hill starting in 2nd or even third gear if I wanted to. now when I shift into 2nd while going up a hill it just lugs along. Since it didn't misfire at all I didnt suspect ignition as a problem. I suspected fuel/carburetion. today I took off the carb and totally disassembled it, cleaned it out, and readjusted all settings to factory specs. the last time it had high end power was probably about a year ago. I haven't noticed the power loss until just recently because I have been mainly just putting along on level ground. I suspect that I might have caused the problem because I had some idling problems a year ago (but no power problems) and overhauled the carb at that time. I'd hate to have to spring for a new carb and I'm hoping someone here has an answer for me. Thanks
