Is there more that I have to clean out?

Yes

Where did the gunk/sludge come from? *Would it have come from the
hose?.

Bingo!

The fuel and fuel tank is clean as far as I can tell and has a
fuel filter as well.

Check all the rubber stuff associated with the carb, hoses, gaskets,
diaphragms (like in the vent cap), whatever. Bits of crud will hide in
places you can't see, so be as thorough as possible. Replace any tired
parts with top quality items. Running it the season in the present
state of tune could be a bit rough on the engine.
