How do you fix a valve stem leak on a lawn mower tire?

I had a flat tire on my mower today and like an imbecile I continued to ride it flat to park it in the garage. After I set the bead with a ratchet strap and aired the tire up there is air coming out of the stem. If I put my stem cap on it stops but I need to fix this.

    Usually you can tighten it down with a valve stem wrench.
