Hi everyone back again for more advice, i have a 1974 cb550 with a Keihin 022A carb set on it when i was working on the carbs i damaged a float bowl valve the small plunger got stuck in the valve body, my silly mistake, the valves are the metal pointed ones not the rubber ones any idea where i can order the same or would the rubber pointed ones do the job, if so would i be better replacing all the valves with the rubber pointed ones or can i mix and match thanks for any advice you can give me cheers.
