Thanks vccomm, yep I have the blade plate still fitted. Do you think it might be the pull "zip starter" ? It is that that I repaired originally among other things. But I can't get my head around how it could be the zip starter. Surely there must be someone else who has had a similar problem? The crazy thin gis that I had it starting fine, and running fine until it just decided to do this pull back! (ps: I am now a bit scared of it.LOL.) [Linked Image]
