I can’t find a spark plug chart showing what plug your 1.2 hp Muncie Junior,
single cylinder is suppose to take.
Is it a 14 mm or 18 mm plug?
Just found this plug on the net showing it’s 14 mm. Not sure what to think about
the “Radioactive” deal, lol.
Firestone F-80 Polonium Radioactive 13/16″ Hex Electrodes Spark Plug 14MM
I would think that 1/4″ gap between the end of the spark plug and anything metal would
be absolute minimum.
Maybe someone will have a chart showing alternative plugs.
Prepare to be boarded!
