Hello!<br /><br />Engine: 1977 Evinrude 85hp V4 Model 85793, S/N J0005666<br /><br />I purchased this engine from a gentleman who says it had not been run in a little over a year, but was running fine. I've changed the gear lube and checked the water pump. <br /><br />I am able to start the engine- it back-fired once or twice but does start and will run with the warm-up lever raised. <br /><br />However, when I try to fully lower the warm-up lever or put it in gear it dies. Any ideas what might be causing this to happen? My thoughts are clean the carbs and perhaps de-carb the engine.
