    Brain Teaser! On Saturday good spark was on upper cylinder. No spark on lower. On Sunday it was reversed.

    Evinrude 1977 6hp #6704M with CD ignition. Upper cylinder has great spark. Lower has extremely weak to none. What can be the cause other than coil if anything?

    THERMOSTAT NEW ALSO. ALTHOUGH WATER FROM WEEP HOLE IS NOT HOT. NOT SURE IF IT SHOULD BE,

    Can incorrect carburetor float level cause lower cylinder to foul spark plug? Head gasket new, fuel pump rebuilt, new impeller working fine, compression 70 + in both cylinders. Black oil slick in barrel. With clean plugs it starts and runs great but not for long.

    EVINRUDE 6HP 6704M STALLS

    MY 6HP, 1977, 6704M STARTS FINE, RUNS ABOUT 10 MINUTES, STALLS, AND IS VERY HARD TO RESTART. REPLACED HEAD GASKET, WATER PUMP, THERMOSTAT, AND REBUILT FUEL PUMP AT BEGINNING OF SEASON.
