Re: Hook style plug set - What spark plug?
Ok. So I need a plug with a removable nut. The NGK 6BL (3212) is equivalent to the Autolite 216, and it has a removeable nut. I'm guessing it has a M4 thread vs the 8/32" listed on the eBay site above.
Seems Monarch-Supply has some very nice nuts and "cooling fins" in both metric and imperial theads. Beautiful, but spendy.
So much detective work for this flathead youngin. Lol...
