i have an 07 summit which i just put a new motor in. the bearings were tight in the crank and motor took a crap. got it all put back together and runs great but when letting off the throttle it wont slow down like it did before or like my other sleds. looked at the throttle cable and it doesn't have any kinks at all and doesn't seem to get hung up. also changed out the secondary clutch with a differant sled to see if the clutch wasn't letting loose. just cant seem to see why it wont slow down. also checked for vacuum leaks on the carb and couldn't find any.
