Just to clarify, you do not need to run the carburettor dry after every use if this is not practical.
I would do it before any long period of storage.
Unless the outboard is being used regularly in sea water, then I would flush out with clean water after use.
Nothing worse than impeller blades sticking to the pump casing due to salt water drying out.
They are then shed as you start to turn the engine next time out…….we learn by our mistakes.
However, characteristics of engines do vary so so just do what preventative maintenance is necessary to avoid problems.
