I have a evinrude 115 82 ish model. My engine runs great on muffs. When i place it in the water at the ramp and drop the engone sown it dies. I can only start it with the manual choke because the electric is broken. My question is if the buttterfly opens to quick ( less than a minute) will this cause the engine to die in idol? Or is this a engine that needs the carbs cleanned? How can i test it before i spend the money on a cleanning or a rebuild?
