I made this vid. so I wouldn't forget how to put it back together, while I waited the 10 days it took, for a new oil pump to arrive from China. Taking the clutch off was the hardest part, but you can use a special tool to do it, (I used a big 'ammer and screwdriver). Otherwise, it's an easy job and should take you less time than it takes to watch this video.
Update: Still going well in 2020.    • Chinese chainsaw, 4 year appraisal..   ..
