Throtte linkage for old briggs 3 hp

#1
Have a really nice old Briggs 3 hp from 1980. Used to be easy to find old posts on linkage, but when I search they don't exist anymore ( might be me) Everyone refers to the post shop teacher did on the linkage but when you click on it , get " Oops, problem." Does anyone have good photo or link to shop teachers link on the 3 hp throttle linkage. Any help appreciated.
