Take the plug out and crank it a lot of times, right side up and upside down as stated above. Take the plug out, empty the fuel tank, get the piston to the top, wire the throttle open and set the saw with the bar straight up so any fuel can run back out the inlet throat.
After a few days, return the saw to the upright position. DO NOT add fuel. Try to start. it may or may not. This will assure it is unflooded.
Sounds like a lot, but it sounds lie a lot of flooding.
Add fuel and try to start about 4 pulls. Check spark with an inline spark tester. See if the plug is still wet.
If it is and there is spark, you still have a carburetor issue.
Maybe it is working on these saws in the 80s, (and 90s and 2000s, They are like 028s, there is always one still running somewhere!) but something tells me it ain't just fuel.
