I need a source for sheet cork about 8"x8" in size to make a new gas/oil gasket for an old Skil Chainsaw. It needs to be pretty thick to make a good seal. I tried using the gasket material I picked up at the local auto store and it just isn't thick enough to make a good seal. This old saw need the exhaust stroke to to pump fuel so a leak is not an option. TIA
