Is it safe to assume that after pushing the primer bulb a million times
and the said bulb is NOT filling with gas that the line from the gas
tank is clogged? The tank is full with fresh gas/oil mixture

No, I think the usual problem is the bulb itself is cracked.

I would generally agree, however if the bulb is cracked, it seems the
bulb would leak fuel.

They do get weak and not prime but not cracked.(like rubber diaphragms
in old fuel pumps)

Does the fuel line have a shut-off valve that is not turned on?

The bulb pump is double action. When empty and it only has air, the
first compression forces the air out and into the carb. Then when
released, the carb valve closes and the vacuum is supposed to pull fresh
fuel in from the tank. The cycle continues, but now is using the liquid
fuel instead of air.

If the bulb is cracked, the first compression will eject air directly
and when released, will suck in more air. There will be no fuel to leak.

The valve from the bulb to the carb could also be stuck open. Cleaning
the carb should solve that.

You asked about a clogged fuel line. Loosen the tank cap a bit,
disconnect the line from the carb and see if gas comes out of the
line??

HD may have a bulb repair kit.
