Chain saw getting fuel?

My old (1984?) Husqvarna 50 chainsaw stopped running. It just stopped. Have checked most of the obvious things. I have the feeling it's not getting fuel, though the fuel pick-up, etc., look ok where you can see them. Maybe there's a leak someplace I can't see. How can I tell if it is getting fuel? I took out the plug, which was dry. Tried pulling the starter, including with the choke on. Did not see any fuel. Should I, necessarily?

Not seeing it isn't conclusive. Put a spoon of gas mix down the plug hole and see if it will fire with full throttle, no choke. If it does fuel is the problem. Pretty much says put a kit in the carb or get another one. Price of a carb is often cheaper than a full kit.

Have you checked for spark? Generally a fuel problem presents itself gradually but not always.

The spoonful of gas test worked. It even seems to have fixed it! Quite mysterious...

Thanks...

Maybe its running for that short period of time created enough vacuum to cause some debris (additive deposits) in the fuel line to budge ?

Could be a stiff diaphragm that loosened up a bit with the initial running. It may show up again after the next sitting period.

Check for damage/rot/broken fuel lines.
