    at idle speed do all four spark plugs fire or only the top two. I know only the top two get fuel under 1800 RPM's, the bottom two kicking in over 1800.

    I still can't fix my problem of not getting over 2000rpm's two switch box changes haven't fixed it. Some say it can't be the trigger or the stator that is the problem some say it can be.
