Hello Jan.
Yes it is entirely normal, and it happens because of the very steep downdraught angle of the carburettor, ( 38 degrees). This puts the level of the petrol in a full float chamber above the level of the pilot airway, and so the petrol dribbles out until the engine is running, when the air being sucked in through the pilot airway stops the flow.
So many Scott carburettors have their bottom union nuts badly chewed up by unknowing past owners taking bigger and bigger spanners and even monkey wrenches to the nuts in vain attempts to stop the leak.
At least it washes the flywheel clean of oil every time that you run the engine, but it is not a very endearing little quirk of the marque!
Best wishes, Brian Marshall
