    1975 70hp model 70573E Starter questions???

    A few electric starter questions....1976 70 hp

    I need help...I don't have a "Mercotronic" or "Stevens" tester.....

    If I did have one, or could find one, I wouldn't be posting this question....it beats the hell out of me why the written instructions for the 70's motors rely on particular "models" of "testers" when it comes to troubleshooting electrical ignition problems in these early motors.....I looked "on...

    Carb cleaning???

    I'm not holding out much hope, but does anybody have a special brew they use??? I'm finding the new environmentally friendly concoctions aren't as good as the "old school" types we used to use...Suggestions??? It's for my 1972 Evinrude.

    Spak Plug question...

    My old motor (1972 50 hp Lark) service manual lists 2 different spark plugs (both flat, surface gap type) as OEM replacement plugs....when I replaced the plugs that were in the motor, I replaced them with regular type adjustable gap plugs of the same number that I took out (they are cross...
