"1979 85hp evinrude 85999R Rebuilt carbs,new fuel pump, 4 new coils wires plugs gas line and bulb. After the carb rebuild it seems to run rough to me. I only have run it on the muffs with hose. IS it supposed to run ruff this way? Being my first boat I was expecting a smooth running motor like a car. Haven't tried it in the lake yet to see if it runs differant."

"Running on muffs for other reasons that flushing the engine, is mostly a waste of time.
Run in a barrel or at sea."
