I learned a valuable lesson about the value of one's time... Thought I'd share my ordeal on here.
Customer brings in his 361 says it died in the cut. Ran fine all day but now it won't restart. I actually get it to start when I pull the deco valve out. But I say why don't you leave it here let me look it over make sure it's alright (already thinking to myself it's leaking air somewhere).
Fast forward 2 weeks when after a few back and forth phone calls I tell him I think either the impulse or intake boot may be leaking, evidenced by audible leak nearer to those than the seals. But I have to take it apart to look & plus it's going to cost you this much, proceed? Yes, do it I need my saw for work.
Pull the intake boot (not easy on a 361), it's fine... Impulse, fine. Replace it anyway but use the old boot. Finally pull the clutch & flywheel, thing won't hold vacuum/pressure. Readjust my exhaust block... Still won't hold.
Finally, finally find a tiny amount of bubbling coming from the muffler side screw hole of the oil pump. Think okay, found you. Tried to Dirko the screw hole and while it slowed the leak it didn't slow it enough to consider it a pass.
It's gone way past being worth my time at this point. I can't split that kind of case & once I ruled out everything replaceable I should have been done. Nevertheless I wanted to be able to tell the customer what's wrong with his saw. Still not totally sure what the issue is other than the leak issues from the crankcase somewhere, either gasket (doubtful as I can see no bubbling along the seam) or the case itself has a little hole in it. Saw will run but will probably keep dying in the cut until it gets so lean it seizes up.
The moral of the story: don't turn into Captain Ahab over a chainsaw.
