Just get a full tank of petrol and go for at least an hour and a half run on various roads and speeds.
If she started and is idling well then leave them until it is due service.
If there is no service history do a full service!
Oil, oil filter, airfilter, clean carbs, brake fluid, check coolant level, check brake pads, inspect, replace tyres and spark plugs.
The reserve on the tank is just a lower intake in the tank.
Say the "on" pipe is 5inches hight, and the petrol level goes below that you switch to reserve which is flush with the botom of the tank letting you use the las few litre of fuel.
Hope I explained that right.
