Carb leaking and overflowing

[houseowax]

I'm completely new- to mechanics, to motorcycles- everything. So bear with me, because this could be really obvious. I've searched all I could and have come up with nothing, here goes:

I have a '63 CA77. I cleaned the carb but did not replace the jets or needle as everything looked pretty clean and workable. I did replace the float bowl gasket. I rebuilt the petcock completely. Fuel is flowing from the tap freely now, so that problem is licked, but all of a sudden when I open the tap the bowl overflows. It's not from the hose, it's clearly overflowing. I haven't made any adjustments to the carb float; I can't think of any logical reason this happening.

When it does start it idles high- almost at full throttle. I took the carb apart and made sure my throttle is freely sliding and it appears to be. Maybe the cable is kinked or sticky; I'll have to look into that.

Four things that come to mind. Improper float height, something caught between needle and seat, worn out needle and seat, or float hanging up on new gasket. you can bend the float inwards by hand, or trim the gasket for clearence.
