hey,kahn,,i didnt do that to mine,,and never had a problem,,,if you feel you need to,i wouldnt completely dissasemble,but just remove the carb,and reed block,,spray it out with wd 40 ,let the drippings fall on a clean paper towel,to see if any shavings show,,you can do the same in the cylinder ,,,make sure you use a bit of blue loctite when you re assemble the carb and reeds,but this is only if you feel you need to,,ps i paid the same for mine...
