Thanks, I will have another look at them tonight and post up some pics. The standard was partly seized, it had a ring of surface rust at the top of the bore. Just enough to stop it from going over TDC, I have fitted new rings and honed the bore. Thought I would add the starter at the same time. I had to file the 020" ring gap a bit to fit them, even though they were at minimum clearance. Will hopefully run it tomorrow and see how things are.
