Sticky butterfly valves


rerb

Recommended Posts

Hi, The throttle on my b12 doesn't return when let off, I thought it was a cable/tension issue but after replacing them I noticed that the throttle linkage on the carbs barely returns when disconnected from the cables. I cleaned everything up with carb cleaner and sprayed some wd40 on the outside linkage but it's still stiff. Is there a way to internally lube the valves without getting lube all throughout the carbs? thanks.
