Getting ready to order some more parts for it later today.
Why order parts when you dont know whats wrong with it? If it was a clearance issue it wouldnt have gobs of compression and then none IMO. I once ordered a popup piston from lil red barn for my CE670, it didnt make over #110 compression. Replaced it with a Meteor that made #155. Both with no run time. Tear it down to id the problem if you can, then order the parts you need. Beleive me, I've ordered parts I thought I needed before id'ing the problem, only to have some parts leftover. If you're working on saws for a little spare cash, every penny counts. If you're not, well then maybe you can afford to do it that way.
