I am looking at a boat with a 120 lehman While starting the engine on the hard, it runs smooth really at any rpm. Trouble is it wont idle down below 1030. Removed the throttle cable, backed off the low idle speed screw, same thing. Too high to shift, so sea trial is out til problem is resolved.
The boat has sat on the hard for a year. 400 hours in last 25 years, 1500 total hours, 1980 vintage. injector pump oil is clean and full, but maintenance schedule unknown. Injectors, valve service also unknown. I called Brian Smith and have a working theory, but I wanted input from the group, Thank you in advance for your advice.
