    Could be a blown head gasket.

    The HRX uses a GCV190 engine, which is a diagonally-split block design (see image below) and it does not have a head gasket.

    White smoke would indicate oil is getting into the combustion chamber, likely from worn-out cylinder wall and/or piston rings.

    Best to have a Honda shop check it out and give you the specifics.

    If the rest of the mower is in good shape, it may be worthwhile (cheaper/faster) to just replace the engine. Certainly less costly than a new HRX...


    Caveat: I work for Honda, but the preceding was my opinion alone.
