I bought this Craftsman lawnmower second hand, and when I
got home, the mower looked even nicer than I thought, but
had no spark plug. I took plugs out of my two old mowers
(which don't work or don't work well) and the hole was too
big for them. I went to Sears and all the plugs they had
for sale had the same size threads as the ones I had
tried, 1/2 inch in diameter, which I guess is 14MM.

I think the hole is 18MM now.

Just weld it shut, then drill and re-tap the threads.

Um, he was looking for practical advice. Meirman, forget
Sears, go to an automotive parts place like Autozone or small
engine repairman. They should be able to help you.

What's ****ing impractical about that? I do it all the time. Just weld it
shut and redrill. Use MIG or TIG, take your time to avoid voids (pun not
intended), then drill it and thread it. Use an end-mill to spotface the
seat for good seal.

piece of cake.
