thermoquad help

the plugs dont look new anymore. i did 3 things yesterday and it went from bad to awful. i drilled the jets 1 size, then i went one more size. when i drilled it one more size i decided to check the float hieght.
i set it to 1" from the gasket with the lid up side down.
i also sprayed the passages with carb cleaner and blew it all out.
now the plugs look wet and are darker now. not black but dark. it doesnt want to start, and it drives like crap. sure seems like a bad needle and seat or float. i dont see how when they were fine. i guess i somehow damaged either in the process. i think the surgine can be it flooding. its no longer popping.
