Plug looks a tad off but ok.
Before you strip a screw I suggest you put a good #2 bit in the head of the screw then give a solid
rap with a small tool or a tiny hammer. It can make it a touch easier to back out a stubborn screw.
As to the generator cover there is a service manual linked on this forum somewhere. Download and read up.
Be careful about stripping anything. There are lots of tricks to preventing that or dealing with something that is starting to get stripped so if your in a corner then post and wait for response.
I'm about to nod off so good luck. I'll stop by the forum tomorrow.
