Hey guys, currently rebuilding the carbs on my 76 cb550, 087A stock carbs.bought the dealer carb gasket kit, and I have two extra o rings. I think. Each kit came with top carb access cover flat gasket, bowl o ring, 4 fuel T o rings,carb drain oring, and a smaller than the drain oring, and one slightly larger and skinnier. Any ideas on where these go? Thanks!
