First time post! I have a honda hrr216 that would not self propel. So i took apart the transmission (added new wheel bushings to try and make it roll backwards as well) adjusted cables, etc. To no avail. Finally I took apart the handle mechanism to discover a filthy roller pin and cable. If I pull the pin and cable self propel works so this seems to be where the problem lies. However i cannot get this dadgum pin to stay in position to where the brackets surrounding the pin will fit the pin in the grooves which allows the user to twist the lever,pull the pin, and move the mower. I am really not sure why but the pin just goes sideways or does not stay within the grooves. Does anyone have experience with this? Any tips? Thanks in advance.
