I got here a bit late, but I was going to say that if the engine turned enough for you to know it had good compression, and it was just the throttle barrel stuck, then just hit it with some fuel and wiggle by hand, no disassembly necessary. Though you do want to make sure the airbleed hole isn't blocked.

The proper setting for the airbleed screw will be set by running the engine and seeing if the low end is too rich or too lean. For a starting point, try having the screw cover about half the hole.

The throttle stop screw should be set so that the barrel moves freely with out binding. Personally, I always set them so that the barrel can be fully closed by the throttle servo, killing the engine. So that usually means getting it just far enough in to the carb to keep things from falling apart, but allow full, free movement.
