    1972 Johnson 9.5 No spark on either plug.

    what dos that mean ? If the coils are set too far back from the magneto there won't be any spark at all, isn't that the problem ?all those new parts and still no spark-kill switch on that model ?

    1972 Johnson 9.5 No spark on either plug.

    easy way to test- 1st before you put flywheel back on check that the shoulders of the coil are lined up vertically EVEN with the outside edge of the mounts- if back too far will not give you a good spark.All good there put on flywheel and nut. Remove BOTH plugs from engine but plug in plugs to...

    2stroke Johnson 4 hp tuning

    When it dies pull your spark plugs-will tell you a lot. If wet and "black looking"then too rich- CARB,. Light brown and dry-no/not enough fuel CARB. Make sure RIGHT PLUGS and check gap-should be .040. For your carb turn adjustment screw in SOFTLY until stops and OPEN back out 1/2 turn.If won't...

    1979 Evinrude 55 hp will not run full speed without choke.

    Next time that you're out open the fuel tank ( safely) just a crack when it starts to bog. Was on a fishing trip and one of the boats was doing the same thing, buddy told me to do this, took right off lol. If it opens up with the choke on that means that it can handle the fuel flow so not timing...
