Not strictly Vincent but I'm sure someone here will know the answer. I've recently got a 1937 BSA Empire Star and am tinkering with it over the winter. After having problems starting ( it wouldn't because of badly adjusted tappets), it now starts easily and idles well once warm. The thing is it, occasionally misfires when idling. When it does this, a spark jumps from the nut on the centre of the drive end cover of the mag to earth with a healthy crack!
I haven't ridden the bike yet so I don't know how it performs under load. Any suggestions?
