This not only goes for those who are rebuilding a carb, but all those cruisers trying to pass emissions like mine. Only trying to emphasize that when I went through this my plug was not drilled out and I ended up trying to find that little bastard expecting it to be a pre-existing screw not something covered up from the factory. Must have tweaked every screw on the carb to no evail.
Just trying to help.
I apologize
