Short video describing how I removed the rusted spark plug from the cylinder head. I didn't show the actual removal because I didn't have a stand for my phone.
I suggest before you sandblast the head that you reinstall that or a sacrificial plug. It's probably not your first rodeo though. BTW it looks to be a 14mm x 1.25 pitch or slightly less than 9/16 in. If it was mfgrd. in Canada probably a metric.
