You guys got me thinking with this thread. Yesterday I was finally down to 1 saw stripped on my bench. I have a max of 2 at a time, to keep from loosing parts, and to actually motivate me to FINISH SOMETHING.... So I walked over to the project shelf. There is that 1-10 mac needing a new top-end, Nah. Wright 122 needing a bunch, Nah. Lancaster needing fuel line/carb/filter, Nah. Husky 77? It's barn fresh, but has good compression at the rope. I gave it a look, and decided it is time. Magnus says it's a turd. We'll see how this one turns out. I've never run a 65 or 77. It's 80cc's and a Husky, can't be that bad.
It pulled 165 PSI with 5 pulls. I stopped there, because I was having trouble holding it down. The top handle is pretzeled, so I already had taken it off to get at the spark plug. The SEM ignition throws a nice blue spark. I nearly threw in the towel when I found that the ENTIRE bottom of the saw was JB weld..... It appears that the case gasket was leaking. I chipped if off after splitting the cases. It took nearly an hour. The one time I wished the JB would not stick, it stuck quite well.....
I got this saw in a batch of 6 from a friend. He is a farmer, and these saws are the ones they have killed over the years. It is very interesting for me to try and figure out what "killed" each one of these. In this case, it was two things:
1. Bent handle.
2. Oil pump inlet screen and tank clogged with debris. Then the pump siezed, nylon gears sheared, and B&C got wasted.
I will post my progress as the rebuild goes on. I plan on this being a good firewood saw, so no repaint this time.
