hi all,
just wondering do anyone know if i have the right carb on my replica road rocket its a monobloc and has 389/203 stamped on it what do these numbers mean! the bike was originally a 1960 golden flash any info would be great also what would be the best setting for the needle 1 2 3 or 4 notches as it seem to be running slightly rich as the plugs are a bit black regards alf.
