You can check the float if you want, but if the float is stuck, the
sucker won't be starting up 'easily' at all, it will flood out and stay
that way.

You will also see gas pouring down the carb throat if the float is stuck.

You mentioned running out of gas? Have you opened the top of the carb
since then?

Sometimes when we run out of gas on our 80's 258's the high vacuum will
suck carbon bits out of the charcoal canister which can do strange
things inside the carb. Black chunks everywhere.

I know a few that even use a clear gas filter on the carb vent line to
stop this because they run out of gas too often.

Now that was something that brought back memories. i.e. this is the
SECOND time I've cleaned this black crap out of the carb, where is
it coming from??

(At the time I was not aware the canister had chunks of stuff in it)
But that was easily fixed by putting a simple trap in the vac line.

Is this a steel or plastic gas tank? Running dry can stir up the rust on
the bottom of a steel tank too, but your charcoal cannister theory has a lot
of merit.
