Hello to all. I have a 1969 Johnson 85 HP Model 85ESL69S and having a problem with the base plate assembly sticking or binding and making the throttle not return correctly. I have taken this all apart cleaned and re greased and at the time did not see anything I thought was wrong with any of the parts that would cause this binding issue. If I just work the throttle back and forth with it sitting in the driveway it works great and have even run it but was unable to get it to bind at that time. When taken to the water and run for a while it does it now every time. Anyone else experience this dilemma with this particular motor or another? Its almost as if something is getting hot and expanding causing it not to return as it should. When you push the advance lever back by hand to the idle return position it is very hard to push back by hand. Could it be binding on the distributor cap assembly maybe where it fits down over the base plate? Not so sure what else to do or replace at this time to help correct this issue. Once it sits in the garage overnight and you go back and work the throttle it works just as easy and moves the advance lever back and forth as it should.
