On the front starboard side of the engine there is a throttle bell crank. The throttle cable attaches to it. It is located on the forward end on the high pressure fuel pump. It has a pivot point with a smooth shank and threads on the end. The nut does not compress the bell crank so it can rotate. I removed the nut and added a spring washer over the smooth part. The spring washer gives it a little friction, but still allows smooth movement. A spring washer is very thin spring steel that has a slight curve. They are very common on aircraft, but I don't know if a hardware store would carry them. You could probably use a split washer and maybe some thin flat washers to do the same thing. It may take a few combinations to get it right. It has been several years since I did this and it works great. The throttle is easy to move and stay put. Don, #6293, M-18, Niceville, FL

One of the suggestions was to put a cable clamp on the throttle cable down in the engine compartment close to where the throttle cable connects to the throttle control on the engine. I have had the top of the Edson unit apart once and thought I had fixed the engine throttle control problem but it did not last. Mine will not stay at a setting above 2000 RPM. I have a piece of shock cord on the Edson pedestal which keeps the throttle at whatever RPM I wish up to 2800. Not pretty, but it works. Maybe I will try the other solution one of these days.

My 1985 model does not. Though there is a dent in the casting where a drill and tap could be used to create the threads for the bolt. If you go to: http://www.edsonmarine.com/support/PDFs/installation/EB396EngineControlInstr.PDF on page 5, second picture under 11. The throttle is on the right. Note a 1/4 bolt hex head just to the right of the bushing keeper screw.
