I have two of these carbs which I have been told are speedmaster

[derek owen]

I intended to use these but change of plan, too large for my need. in metric they have 15mm spigot and a 13mm venturi, Would like to know what size motor these would fit so that I can get a for sale ad up, My gut feel is a 67 /80 ? One is new other is good as new but used, Any ideas of selling price? happy new year from across the pond
