It's more likely being 50 years old that kills the plastic floats!Since the carbs are very old you may also have the brass float needles. They were obsolete a very long time ago. If you want to keep going with those carbs, you need two of RKC/561 if it's a 750 or RKC/602 if an 850. You also need two of 622/055S (float bowl) and two of 622/155 Float bowl drain plug. And, possibly two of 928/603 if a 750 or 928/6035 if it's an 850. And finally two if 622/122-106 Needle Jet.Once you have all that installed, you'll still have non-Premier carbs made of Zinc alloy but they will be the best they can be. You will have spent over $200+shipping. That's about half of the cost of a set of new Premiers.
