My son just purchased a 1988 20 hp Evinrude on ebay advertisewd as in mint condition. The motor came and under the motor cover it looks to be in very clean condition. He took it out and ran it on the lake to find it had a yawl or hesitation when accelerating, but it ran good at top end.<br />Also the idle was very rough and it stalled when trying to trailer the boat. He adjusted the idle mixture and was able to get the boat on the trailer. The next time out the hesitation was gone, but the idle is still quite rough. Also the ball on the fuel line never quite gets to a firm condition when pumped. Any hints? Carburator? Fuel Pump? Gas line? Where do I start to solve his dilema?<br />Thanks, GeorgeN
