Unplug it if you don’t wanna cut the wire off, and put the box end of the wrench on it. That way you just put the wire through the wrench. Or use a pipe wrench, might get better leverage that way anyway.Think I'm gonna go get some MAP gas and that 22mm wrench from HF. Only thing tho--since that nut started to round, the 22 might not be snug enough and slip. Any suggestions about that?
