The old gasket appears to be of a fibrous nature, kinda like particle board, but smaller and denser, and very dark in color. The blue silicone may have been used for a vacuum leak and fuel leak...fuel leak for sure...as I saw it pool on the bottom of the intake and leak out the side by the accelerator pump. (it is tight now, as far as fuel leaks go) If partsshop carried this gasket, it would be great, as my hours and the dealer hours do not match at all...unless parts is open on saturdays, which I highly doubt.
I would like to avoid getting a new carb, besides I don't think they make these anymore, and a Weber carb would cost me more than I paid for the car.
