OK. Cleaned the carbs on my '78 CX500. Used Larry's book. Put them together taking the one turn of the choke spring as per the book. When I move the choke cable, the outer plate rotates but the inner shaft doesn't. Do I need to take more turns on the spring? Is it just the tension on that spring that closes the choke or did I miss some mechanical connection? When I rotate everything by hand it closes fine.
