but why 10mm??? it's smaller tan the 13mm stock cag setup.
RD, i've got a 16.5mm race ported walbro with the lot, i'd say that'd beat your 10mm, and my stock piston port carb also had the adjustment screws. but anyway, enough of screwing up your 4 sale page.
everyone with a stock cag carb, it's worth buying RD's carb you'll definately notice a difference
