1982 7.5 Hp Merc. Serial 6111493. Motor was used as demo in Vocational School. Tear Down put together format. As a result parts may be missing. I have motor,and have purchased the repair manual for the engine. However one problem area is the carburetor linkage system. Diagrams in the manual do not show parts for this system in diagram form. I can't tell what might be missing from the system for proper operation.
