    fuel connectors

    I have what I have found is called the 'Merc' connection to my motor but what I see is called the 'OMC' connection at my tank.<br /><br />Is that a problem?

    soaking carbs

    I'm about to attempt to de-carb a motor and I figured I would 'soak' the carbs overnight while I was at it.<br /><br />2 questions:<br />1. Do I soak the carbs in the SeaFoam as well? Or carb cleaner? The only carb cleaner i can find is in the spray can, nothing pourable.<br /><br /><br />2...

The guy selling it supposedly cleaned and/or rebuilt the carbs, replaced the water pump impeller, replaced the starter and cleaned the plugs after it had sat up for the last 5 or 6 years.<br /><br...
