Hello everyone,
I purchased an old Jon Boat last year with a 1976 Mercury 7.5 HP motor. It ran OK last year but constantly had problems with the pull string and carb. Anyways this year I cleaned out the carb real good and replaced gasket seals. I also replaced the starter rope string. The motor is idling and running pretty good now. However I noticed that when I go in full throttle I hear almost a metal clankety rattle sound coming from the motor. Its not a knocking sound or anything. It almost sounds like a piece of metal just bouncing around somewhere. Any ideas on what it might or could be? I've already taken the pull string assembly apart and put it back together again in hoping this may clear the sound, but I won't be able to test it out until this weekend. Thanks in advance!!
