Got out and made a quick video since it's a beautiful(yet very windy) day.
Having a little fresh fuel in the system overnight must have done something, because when I checked it out today the saw can now reliably start on a few pulls with the choke on, no need for priming.
It's still obviously in need of some love and care though. Usually need to hit the throttle every few seconds to keep it going, though there's times like in the video here where it will idle on its own for up to a few minutes before it eventually bogs down and needs another hit of throttle or it dies.
Also, this carburetor confuses me. Am I seeing two fuel and two oil lines going on here? I also had a minor incident when I turned that thumb screw on the left side of the case that says "<-- Open".
I thought this looked like it was to control the flow of bar oil, but the moment I started turning it while the saw was running it immediately got stuck WOT. I had to quickly hit the off switch to make it stop. Odd.
Anyway, here's the video. It's running a bit lean, right?
I think a rebuild kit in the carb & you'll have a good saw.
