    I bought a very dirty Honda HRS-21 mower. It is hard to start-
    must be choked even once warm. It ran fine when I got it. I
    power washed the filthy underside, changed oil, put in a new
    spark plug with proper gap.

    Following this, it would not start unless I poured gas directly
    into the cylinder. Once that was spent, it would quit.

    I proceeded to take the carb, air cleaner housing, etc. all apart
    and clean thoroughly. Put it all back together and it runs now
    with choking at startup, but runs very rough with an inconsistent

    Could this be due to:

    1) Moisture in the coil/ignition wire connection under
    the deck from the powerwashing.

    2) The current state the mower is in without the
    blade on (being sharpened).

    Gas is new, gas tank has been washed out, carb has been
    cleaned out.
