Wright Saw

So, I got a couple new chainsaws recently. Was working on them for a customer but ended up getting to keep them because of how much the repairs would cost.
One is a new-ish (2013) plastic Homelite 3816 C chainsaw, with carry case. It idles, but won't rev up, even after replacing fuel lines/filter/primer bulb. Gaskets/diaphragms looked fine, so I'm thinking a check valve or welch plug went bad/is leaking, so it needs a new carburetor.
And the other is my first Stihl. It's an 031 AV, with a serial number, made in West Germany. Every part I can see on it (except for the Oregon chain) is genuine Stihl, so when replacing most parts I'll only use Stihl. From several (77) cast date wheels on various parts, I'm assuming it's a 1977. It has anti-vibration, throttle lockout, and a hand guard, but no chain brake or heated handles.
Before I got it running, I checked the compression, and I remember it had around 160 psi. I rebuilt the carburetor, installed new genuine Stihl fuel lines, filter, AV buffer, impulse hose, cleaned the fuel tank, freed up throttle trigger, and cleaned the mesh air filter. It does not say electronic on the tag and there is no "K" symbol on the flywheel to indicate electronic ignition, so I would guess it has points. But, it's always had good spark, and I've never pulled the flywheel. So, that leads me to believe it may have electronic ignition.
I started it once (took many pulls since it had been sitting so long) and it ran good. Idled and revved up fine. While idling, the saw stalled out. I looked later and saw that one of the clutch linings came off the shoe and wedged itself between another lining and the drum, causing the clutch to stay engaged to the sprocket. The saw probably stalled out because of the load at idle, and I haven't attempted to start it since. I'm going to try some new shoes instead of replacing the whole clutch. It also needs a bar, chain, sprocket, and some other little things to get it fully functional.
Coincidentally, it takes 3/8" pitch x .050" gauge chain with a 16" bar, same as my Homelite SXLAO and Husqvarna 36, so chains should be interchangeable between the three of them. The bars, however, are not. My new plastic Homelite also looks to have 3/8" pitch chain and a 16" bar.
I will post pictures soon, and update this thread with progress I make on fixing this saw. Thanks for reading
