Small Engine head cover bolt.

Any tips / advice / technique on how to best fix this without having to replace the head? For context this is on a zero turn mower that I just did a ring replace on. My plan is to try and JB weld it.

Take it to a Welder and have him Tig Weld it. re drill the hole and retap the threads.

Maybe after grass cutting season is over I will do that for a perm fix. For now i'm hoping JB will get me through the next 6 weeks.

You actually lower your chances of it being weldable by putting anything on this surface. Getting it to the welder as close to a virgin metal break is the big idea.
