The first thing with any project is to see what state its actually in. I learnt a long time ago
with disc cutters because of all the stone dust the engines tend to be knackered. This one
has proved to be no exception. The cylinder and piston are chewed up, the main berrings
have gone, the clutch berring has also failed. Suprisingly enough though the crank feels
ok. This would entail quite considerable expense, however as luck would have Stihl used
the same engine unit in their 08s chainsaw and normally these tend to be good mechanically
due to the saw dust being harmless to the engine. In my store ive got a broken one of these
so hopefully I can have most of the bits off this doner.
