Yep.  It's old.  But it's my trusty friend that has always performed well.  After being in storage for 5 years, now when the sparkplug is out, it spins over just fine.  With the plug in, I can get it to turn over once and the compression feels normal, but after that one rotation, it seems to back up against a ton of compression. Someone else posted this problem with a different model Stihl saw and got replies mentioning a possible faulty starter mechanism.  That doesn't sound right since the starter pulls as it's supposed to with the sparkplug out.  It's a compression issue since I can feel it backing up against impossible compression with the plug in.

Any ideas?

Same plug that was in it?   

Hydro locking up with some kind of mix bypassed into  crankcase?

Pulled muffler?  Check to see if any ring rust or carbon falling into bore?
