Hello, everyone.

I have a Murray push mower and it has a pretty easy-to-remove air filter assembly. The only trouble is that I can no longer tighten the air filter housing bolt. It appears the threads have been stripped. This means that when the mower runs, the vibration causes the air filter housing to come loose.

There are some pictures below. Does anyone know how to fix this?

Thanks!
Erik

This is the bolt:




And this is a top-down look at what the bolt screws into. I can't tell if it's screwing into plastic or if there is are metal threads beneath the plastic:
