Thanks Mark for posting I was thinking the same
Here are pics of Edison 13 and 14 plugs.
Both can be hard to find, especially the 13s.
I have a set of 14s in Betsy and they run great, they run hotter and stay cleaner than Champion X's.
I'm confused. Which of the plugs in the first post are 13s and which are 14s? I would like to try a set of 14s. Thanks, Bill
I wish I knew what numbers would fit my dad's Paige? But I don't need them, and can't afford them right now anyway.
