Thanks to Grant A. from Facebook. He's been chasing low oil pressure at idle and had tried numerous things, even replacing the big O ring behind the points housing. If that's out of spec, it can cause Oil Pressure issues.
He removed and cleaned the oil pressure regulator and in doing so:
"Removed the oil pressure regulator and cleaned it. Measured the spring length in the relief valve. Below spec. Replaced it with a spare spring from my spare engine, bingo!!! Oil pressure is all good!"
Spec for regulator is 58.2mm. Service limit 53.5mm. Actual spring length had reduced to 51mm
Worth keeping in mind, Oil pressure regulators don't last forever.
