The same thing happened to me when I was doing the Carbs of a 1973 Honda 350 Four, the O Rings were in bits, but the rubber item in the kit I bought were feck all good on the present day fuel. Even the hoses they supplied were crap. Had to do it all again 2 months later. Lost money on that job and trying to explain to the owner was nearly impossible. Emailed the suppliers of the kit ad got no satisfaction. Owner was none to pleased. Ever since I source the correct seals locally and use an OEM float bowel gasket. Many bearings suppliers also do O Rings but luckily I have a dedicated seal supplier within 12 miles of
my house.
How did you check the float levels, did you just turn the carbs upside down?
