You will need to clean out the fuel tank, fuel line filter, needle and seat, float bowl, main jet, emulsifier, idle jet, idle disharge orifice/idle mixture needle, and all of the fuel and air passages. You can get detailed instructions in this thread:

Note that your problem is not, or not just, a blocked idle jet as in that thread: you have a major blockage in the fuel system or carburetor, and because you know you had corrupted fuel in it, you now need to go through the full process to get it back to running like a Honda.

Please report back after exactly following the instructions in the other thread.
