Yes, check your carb bowl to see if there's fuel. Dry spark plug = no fuel getting into cylinder. If the bowl has fuel in it, one or more of your jets is probably clogged. The last carb I cleaned out, I used carb cleaner spray and sprayed it through all the jets and openings in the carb using the small plastic tube that fits on the spray nozzle.

As for those other tubes, sounds like some sort of funky emissions control stuff, maybe to scavenge fuel vapours from the tank? You can probably remove all that stuff and plug the connection to your intake manifold, don't want any vacuum leaks there.
