Hi Guys I’m using the NGK Iridium BR10EIX and had ground down a socket, but it broke. Have others: 1. Ground of the eyebrows? 2. Found a socket that’s perhaps forged instead of cast? Whats the wisdom? Thanks people. Steve Izett -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
