It was just a thought.  A way of improving knowledge and experience that makes one an expert.

no i did not refit the coils. i did do nearly 200 lovely miles Sunday. it has a small missfire at around 3K like a hesitation but other than that it runs great. i will re check the timing when i have five Min's.  I called in Abergavenny on Sunday and when i described the hesitation at 3k a chap there who said he had a Honda dealership back in the 70-80s said the autoadvance springs were a bit tired. and a fix they used to do back then was to chop off the eye of the spring and fashion a new eye thus shortening the spring by a tiny amount made up for the slack in the counter weight. has any one hared of this?

No but if you could get hold of a strobe light you could check if the auto-advance is working properly, which might be better than trying something irreversible...  :)

Agree with Tom.Seem to remember there is a topic about this on the states site
