My '83 70hp Evinrude will
My '83 70hp Evinrude will run at 2800rpm WOT during travel for about 20-30 mins. Then all of a sudden jump up to 4200 by itself without touching anything. Before starting I pump the primer bulb about 10 times and the bulb never gets tight.Is this my problem with the rpm's? What should I do?
