The carbs with the screw on holder use the other type gasket since they can be tightened more. I'd be interested in knowing your source so I can do a bit of research.

They told us that they prefer to use the cork carburator bowl gaskets over the paper ones for the 9-series Bings. They also told us to be careful and torque the 914 bowl bolt to specs and showed us the result of over torque, which can deform the bottom of the bowl causing the brass rods that the floats ride up and down on to splay outward and cause the floats to stick. I have had my float bowls off a couple times and have not replaced the paper gaskets yet. No mention of incompatability with 10% ethanol.

Today's cork is a compound. And YES those OLD REAL CORK gaskets were very easy to destroy. That is one of the reasons why they went to metal 'head gaskets'. Back then you coated the gaskets with INDIAN GASKET MAKER aka Varnish. Now as for the colors: Clear Black Gray White These are standard Sealant & Adhesive types. RED Is considered a High Temp BLUE Can be a High Temp but is also know as a GASKET MAKER. And just to confuse matters GRAY is also a High Temp in some brands. NOTHING is STRAIGHT FORWARD any more.
