Regarding brass floats.... Bring a cup of water almost to a boil. Hot in other words. Take something like a pair of needle nose pliers and immerse the float in the hot water. Brass conducts heat. The air in the float will heat up immediately. Heat causes pressure buildup. If there's a pinhole leak of any sort, you'll see a stream of air bubbles almost immediately. It's an almost foolproof way of testing brass floats. And doesn't require several minutes of waiting to see if there's a leak.... like your method does.
thanks for that👍 the Mikuni is one of the best caruburetor out there, worth a repair.
