    perhaps a better definition of opened

    opened as in "Remove the cylinder head"
    or
    Opened as in "Full Throttle"
    ?

    I think you mean adjust rpms, Idle should stay the same, but some machines need to have the rpms cranked up due to stretching of throttle cable or other similar issues.
    My Walker was maxing at 2500 rpm,
    She really sings at 3600, where it's suposed to be.

    So, how is this done exactly? I'm not big on the engine repair side, so I really have no idea how to do it, but my 13 hp Honda could use a little more RPMs.

    Take a tachometer, and check where you are, and check the engine manual to see where it's supposed to be set.
    Then follow the instructions in that manual.
    ( different adjustments for different engines )

    Thanks. That engine is a little small for the 48" Bobcat w/b it's on, but it runs so nice. If I can get a little more out of it, it would be great. I'm only doing 6 lawns part-time, so I'm not up for buying a new, expensive mower at this point. Hopefully, next year - maybe a small ZTR. We're moving in August and our new neighborhood is all 1/2 to 3/4 acre lots, so I'm hoping to pick up a few of those for next year. Beats these little 1/4 lots around here (although at $35-40 a lawn, I do make good money off these).
