Hello yall,
Recently during an adjustment to my '73 CB550k, while putting the slides back in I noticed by #1(far left if on bike) carburetor round slide can spin in place. After taking it back out promptly I have found that the tab area for the alignment tab is smooth. Can these wear smooth? On another note, is there anything I can do now that this is damaged besides source another carburetor as the slide aperture is off center?
