    Either stamped in the valve cover or on a plate above the muffler is the model and type numbers, Post them. It all depends if they offer a over sized piston. But anymore it's just as cheap to short block or even replace the whole engine instead of rebuild.

    does the cylinder have a ridge at the top? how do you know it's worn. maybe a gasket set,rings,valve job might get you a few more years out of it.

    Exactly. Check shortblock and engine prices. And then check mower prices. May just be time for a new mower.

    If its a valve then a valve job would help you out and be worth it depending on the value of the mower.
