What are you hoping to achieve with the saw?
Seals and gaskets could be tricky to find, bearings may be proprietary too. If you decide to go further, it’s worth having a very good reason to do so, you may be giving yourself a heap extra work both in time and expense.
Did the seals leak? Did the gasket leak?
If not, I’d suggest to leave well alone.
Thanks for the response. Basically, I want to get the chainsaw cleaned up, not restored, and running well. I was trying to figure out the issue I described in Post #13 above, and a forum member said to check the crankshaft seals. The CS was so gunked up with oily sawdust, so I started removing parts to get at the debris, and I ended up where the pictures are. I did clean up the piston, removing a thick baked-on layer of carbon from the crown, and I also cleaned out the piston ring grooves:
Last but not least, I’m learning how these chainsaws are put together! That’s worth the education
