The points had a very small "pip". I dressed the surfaces with a slip stone. I'll probably fit electronic points at some stage.
I'll double check TDC against the valve lift although it's pretty tough trying to rock the car in gear to get the engine moving. There's no room to turn it from the pulley bolt!
I'll also take off the distributor and strip that down. I'd not considered the weights sticking at max advance. I did have a Midget once that had a frozen distributor but that had no advance at all. The distributor has a skew gear drive not a peg.
Thanks for your suggestions!
