A quick update - got the car running fine again..

Pulled the carb, opened the top, didn't see anything obvious. I adjusted the floats a little lower, reset the idle mixture screws to 2 turns out, and cleaned the needles.. put it back on and it runs fine, took it around the block 5-6 times, checked it, then went for a 4 miles drive.. no free-flowing fuel pouring out anymore.

..and it's also not a 95F day out today...

..so I ordered a rebuild kit from Larry Isgro Carburetors on Long Island, NY just in case - been dealing w him for over 15 years now. His first suggestions were the same as yours - adjust floats and check for any debris stuck at the needles.

Thanks again guys,
