Hey All My recently aquired spada seemed to smell rather petrolly of late. I happened to notice this particularly after I turned on the choke and didn't seem to return well. The bike would start and need substantial throttle to keep it running. These effects would normalise after a while Anyway today I removed the tank, and opened up the vacuum compartments of the twin carbs to see if the cable was effective. Well the cable didnt seem to properly open and close the choke valve, in the vacuum compartment. I just disconnected the cable and forced the valve to remain in choke off position. Now the problem is from 4k-9k revs the bike seems to not have any power. Speed stays constant, and gearing up really makes the engine struggle at these values. Only when I completely open the throttle, does it take off like a rocket. So basically the throttle has become "all or nothing" in regards to acceleration. Worst of all it still smells petrolly... Also I disconnected the choke cable from the handle, and when I pull on it I don't notice any change in revs, up or down...which is odd. Would greatly appreciate it if anyone could give me any insight. Also if anyone could explain the principle/theory behind the honda dual carb, it would help immensely. The wikipedia carb schematic does not look anything like my carburetor... Thanks All!
