Thank you all for your hints. As regards loitering in the wrong forum area, can you suggest which is the right one for future
You posted your question in "Vehicle Talk - Non-Morgan".
As it's a question about maintenance on a trad Morgan, you might have been better off posting it in "Traditional Morgans" or ideally "Maintenance and Servicing". It makes it easier for others to spot what the post might be about and respond to it. Not everyone reads every post in every forum.
