    18 hp Johnson no spark

    exactly... as the condenser insulation between the 2 foils degrades the strong EMF kick from the coil can't be saved nor contribute to the generation of spark energy when it dumps back into the coil. Leakage can only be tested under high DC volage has explained in M.Moat's excellent...

    1977 55 HP Evinrude

    carbs usually leak from a bad inlet float operation when rebuilding carbs you must do the blow test on the inlet nipple right side up... air goes in the carb held upside down no air should enter the carb. dont get to hung up on the welch plugs just tap them in properly they...

    1977 55 HP Evinrude

    have you tried shooting some fuel oil mix in the carb directly to see how the engine reacts...if it run whith no choke it confirms the engine is not pulling it's own fuel fuel out of the carbs .

    1977 55 HP Evinrude

    if you have good sparks.... if the carbs are clean....., if the fuel is fresh the engine needs to suck that fuel out of the carbs thanks to the crankcase negative pressure ( aka vacum) during the piston up strokes. when piston come down the pressure builds up and expels that fresh...
