  3. Disconnect rod. Loosen nut from screw. Unplug connector from throttle switch unit. Loosen 2 throttle switch unit bolts. Start engine. Adjust screw to obtain 600 RPM. Adjust throttle switch unit. Reconnect throttle switch unit connector. Perform idle preset adjustments. Reconnect throttle drum rod. Unlock 2 lock nuts and turn rod to obtain a play of .078" (2 mm). Adjust richness at idle.
