Ugh.. tried to change the spark plugs yesterday. Turns out the spark plug socket I bought was a piece of junk. The rubber insert doesn't "grab" the spark plug well, so I had to be really careful pulling the old plug out and putting the new one in. On top of that, the insert was really loose, and after installing the second plug, the insert fell out of the socket while it was coming off of the plug
I had to remove the spark plug to get the insert out. By that time it was starting to get dark, and I didn't want to have to deal with pulling old spark plugs out without the rubber insert in the socket, so I just bolted everything back up. I'll do the remaining plugs once I can find a half-decent spark plug socket.
