Just a remider---Dont forget the thick fiber washers under the screw heads that hold the tap on or petrol will leak past the tap to the carbs all the time, sorry to say i have not found a fibre equivalent to the horribly expensive Honda ones as they are extra thick but have a smaller than standard outside diameter. I have however used what I know as "Dowty" washers which are the alloy washers with the rubber insert normally found at hydraulic suppliers, trouble is they aint much, if any, cheaper unless you are willing to buy 100's
