Turned out there was a partial blockage in the main tap stand pipe that reduced its diameter but didn't fully stop the flow and the engine was using more fuel than the tap could deliver. Taking the top of the carb off when this happened showed an empty float bowl but turning the fuel on produced a flow.

No reserve; just an elbow on the front of the tank.
I have checked there is no blockage. The tank is rust free. A few years ago I gave it a thorough clean and applied ethanol proof TOPAX sealant which is still holding up well. No sign of it coming off at all ...but of course you can't see everywhere inside - even with a dental mirror on a stick!
