Hello, can someone please advise me on the correct placement of the rubber reducer ring which goes between the carb inlet and the air box outlet. There is an alignment mark on the rubber but where should it face as I am having difficulty getting the air box back into please 

thanks very much and help greatly appreciated

thanks, it’s tricky with shape of tank
