i have a 69 johnson 55 hp that misses bad when accelerating slow, has a slight miss at other speeds. seem worst at end of day when in no wake zone. checked last night after loading and water manifold was fairly warm and top of engine-flywheel above stator was HOT. have replaced water pump. also have seen a thread on here that shows hot to install a telltale on this motor, could someone steer me to that thread. any help please
