Kohler Spark Plug Gap Variation

[dgunn]

I wonder how many IHCC owners of the 1x8 and 1x9 wide frames might have missed the different spark plug gap for the starter/generator versions of the Kohler engines. I recently pulled out the manual to look something up and saw that I had highlighted an item, probably 30 years ago now, that I had completely forgotten about. If someone had asked me today what the gap is supposed to be, off the top of my head I would have said .025" and I would have been wrong.
