Hi Iain,
Hopefully the Membership Secretary can answer you question on nearby members.
As far as priming the carburettor: is there a manual priming lever on the fuel pump?
Like any engine, if it has been left for some time, all the oil will have drained into the sump and possibly leave the bearing surfaces dry.
The way I proceed is, to turn the engine over first with the starter motor without the ignition on, so it doesn’t start, then manually prime the pump, then turn on the ignition and start the engine.
