So the cork gasket is the only issue ?

And once you get that out the screw usually is free?

Or do the threads need to be lubed up too ?

I have an old set and am getting ready to flog them.


If you look at the bottom of some baseplates right where the idle screw goes in it sure looks like holley dimpled the base after the idle screw was set to lock it. Rumor has it that that really sticks them in there, I think drilling those would help relieve pressure. Soaking, lube and a small sleeve that fits over the idle screw so one side does not break off will lead to success.
