Just use the plug remover in the tool kit and a 17 mm wrench(if you have the tool kit) Or just use a plug socket,1/2" extension and a small ratchet. I just used a socket and a flex ratchet because of the angled head. You can use a pencil magnet to get the plug out or even a piece of vinyl tubing over the plug to pull it out.I'd stay with the BKR5 or 6 plug.I've tried Iridiums in different older machines and fouled em out. Tried em even in my old Honda with little success. Fouled these high dollar plugs out too. They work best on the newer electronic ignitions. Just my on this one. Others may differ on this. OPT

In my service manual, it says to use anti seize on the plug threads? Is copper good, that is all I have.

This is where you need to be careful! I still have the "L" shaped plug cap remover that I just used the palm of my hand to pop the cap up. Just reach in and work it a little side to side and up,don't break the cap or it's $25 or more to replace. I've seen a lot of em taped up over the years! OPT
