Good morning everyone, I've just had a look at doing that, but it appeared to mean putting a sharp bend in the connector, so I left it alone. Under the cover is a disc made of some kind of thin paper (see new photo attached) - doesn't appear to be gasket material, more the consistency of greaseproof paper - to help weatherproof the points etc I guess? Also, where is the felt pad which should have a small drop of oil? Thanks again for your help.
