After you take the bolt out of the bottom the bowl will come off, it usually has seated itself in the gasket so taping the side of it with the side of a screwdriver handle will get it off.
Look up in the hole where the bowl bolt screws into, where is a jet in there, all of the jets should be taken out and soaked along with the carb body to remove all of the built up varnish and get the jet orifices back to the proper size.
On reassembly, flip the carb upside down and make sure the float is level.
Sounds like you're on your way to many productive nights, glad ya got it worked out.
