I have a 395XP that I picked up cheap. The clutch side crankcase is broken in the lower corner. Can I run this saw as is or will it rattle apart and self destruct. I have included a picture so you can see what is missing. Any and all advice is appreciated. I will probably keep my eyes open for a used case or bite the bullet and get a new case as I only paid $150 for the saw. Everything else on the saw is good.
