Those are not the proper sealers.
The seals are conical shaped neoprene inserted in brass, like the picture shows.
Ronayers has the part, which number is 16030-1007 and cost ~$26 each.
Improvised O-rings aren't substitute for those parts, IMHO, especially is they disintegrate in gasoline + ethanol.
The way to test the valves is connecting a hose long enough to mimic the height level of a full tank above the carbs and fill it up with gas: the valves shouldn't allow any gas into the carbs once the bowls reach the specified level.
This is a good opportunity to verify the level that the fuel reaches inside the bowls (when valves are closing properly).
