Hi Folks,<br />Just finished rebuilding carbs and fuel pump on a Johnson 55Hp commercial outboard. It fired up easily on the stand. However, it idled somewhat fast and had a continuous rhythmic surging characteristic to it. Unfortunately, the stand isn't wide enough to accomodate a water barrell for the lower unit so I had to use the ears. About one minute of the exhaust noise was all I was willing to subject my neighborhood to while enjoying their dinner... I figure any more troubleshooting will have to be done dockside or underway.<br /><br />Any suggestions to get the idle smooth? I'll check for leaks/hard bulb in the fuel delivery path too.<br />TIA,<br />-Jack
