I’ve got a hand-me-down 028 AV woodboss that was my only saw for a while, quit on me, but I’d like to get going again as a backup. I’ve worked on a few small and large engines, but this will be first chainsaw I’ve been into this deeply.
Long story, short - it has compression around 105 lbs so I’m thinking at least rings and maybe piston/cylinder are in my future. Piston looks fine from the exhaust port so I’m not sure what’s up yet.
I’ve got tons of questions, but in the interest of brevity, I’ll just take them one or two at a time.
Currently have the the air box/ handle removed and been trying to conduct a crude vacuum test with a cheap brake bleeder. I’ve struggled to get the intake boot plugged fully but will figure something out. Really want to get this done before I pull the cylinder.
1). What sort of reading (my gauge reads inches) am I looking for and how long should it hold?
