Thanks Gadge. The Cox manual doesn't detail how he lower section of the steering shaft is dismantled. I have had a closer look and under the lower section yoke I can seen a very small hole that is partly covered in paint. Perhaps this will prove to be a small allen key grub screw. I will try this in the morning and post the result. Crikey, you don't let the grass grow under your feet, do you? Just an hour for a reply, WOW! This is for me!
