Interesting!! When I first pick up any new engine and in this case my 592, I always undo the spark plug at home, and I don’t know if it’s good or bad but put back in with some never seize, no good being out in the field and it’s too damn tight! I don’t know why they are done up so tight, mine was way too tight I thought it was going to break. Of late I had the threaded section inside the muffler(another post of warning to look for)that is for the spark arrester screw drop in the muffler, one muffler bolt was way to tight the other two ok, it was taken into a dealer whom removed it also to look inside. And now I have three super tight bolts

T handle I don’t have and a simple Allen key style torx is looking to be insufficient now

Big fella big hands don’t make for easy work thereafter. I understand. I’ve never seen a plug do that before
