As I mentioned in a previous post
it is wise to put some Tef Gel or anti seize on the case screws of the Honda
before you need to remove it.
I finally got the replacement screws delivered after two weeks and as I expected the repair of the pull cord only took about 10 minutes.
I've got some photos what's involved in replacing the pull cord here:
