I have a 1968 Evinrude 18 hp fastwin. The motor starts and runs well. The problem is that it runs "dirty," leaving a significant residue of gas on the surface of the water. At trolling speeds there is a constant rainbow on the surface of the water near the transom on both sides of the motor. When I kill the motor I get a rainbow area of gas about five feet in diameter. What could cause this and how can I fix it?
