Why not just simply drain the gas tank, flush the lines all the way thru to the inlet to the carburetor, and refill with fresh gasoline. If nothing else, you'll eliminate this as a cause. If you have no way to discard the old gas, keep it for cleaning dirty parts.

If you think you might have a stuck float, easy enough to tell. Turn on your electric pump; if it's stuck down (sunk) gas will soon overflow the carburetor bowl vent - something you can't miss. If you think it's stuck up (closed), just open the choke valve and stroke the pedal linkage and look for 2 streams of gas from the accelerator pump jets.

For a wet distributor cap and wires, a spritz with WD-40 and a wipedown works well. And don't ignore the possibility of moisture around the high tension lead at the coil - not uncommon on wet ignition systems to see blue flash from the coil centerpost to the metal shell - try starting in a dark garage and see what you see.
