Looks fine, probably the original.

Replace it with an NGK.

I've switched all my OPE, including snow equipment, over to either NGK IX or Autolite XST iridium plugs. Some will say they make no difference over copper but my fuel consumption on mowers noticeably decreased after switching.

This Autolite XST is the cross-over for your J19LM plug. At $4 for an iridium plug, its a no-brainer over the $6.46 copper Champion.

Just my $.02 anyways...

I will second the nomination of the Autolite Iridium. My 39 year old Troy-Bilt Rototiller with a 5 HP B&S flathead had turned into a 5-8 pull start with a new Champion. It's back to a one pull start with the Autolite Iridium. No other changes were made at the time...
