    Points of interest cylinders one and two share a carburetor as well as three and four share one.

    Given that cylinders two and four both look to be better.. I find it hard to believe this could be a fuel issue.

    Another interesting thing is that when the engine is turned off.. white wisps of vapor come out the carburetor/intake side.  I never seen that before on 120 horsepower Mercury Force but then again I never really looked ?
