I have a 72 80hp that was put on a 1989 boat. The idle lever doesn't move the throttle until it is past vertical. When I push the lever all the way back to low idle the distributer and linkage do not return to the idle screw. The cable is screwed all the way into the cable holder on the engine side. Is this normal or is there any adjustment on the lever end? should the distributer and linkage return to low idle by a spring? There are two places to add grease to the distributer, could it just need to be greased? What kind of grease do you use? I ordered a manual but would like to get this part fixed while I'm waiting for it.
