The old girl is turning over but not firing up. I suspect ignition side of things but can't be sure. Tested for a spark from king HT lead to block and it was weak and orange, not vigourous at all.
I have replaced coil with Lucas gold type, fitted new points and condenser, and made sure baseplate earth wire is in place and looks in ok nick with no improvement.
What would be the next thing to check/replace?
