I'm about to put my carbs back together after rebuild. There are 2 small parts, spectacle shape in thin sheet metal that sit between the carbs. They're listed as part of the assemblies 95 Holder set A and 96 Holder set B.
Mine are broken, cracked through in the thin bit in the middle. They are thin and flexible and don't seem to do anything. The carb operation seems perfectly ok without them.
I can make a new pair, but do I actually need them?
