So, the old mower refused to start for me Saturday. Air filter was new, oil and gas were fresh, and I had just used it the previous weekend with normal operation. I figured the easiest place to start was the spark plug, so I headed down to my small town's parts place and asked for a Kohler 14 132 11, which was OEM. I was told they didn't stock Kohler, but was sold an Autolite which was supposed to be a match. It wasn't a match, so I just cleaned the old plug and the mower fired right up. I did some research online afterward, and it seems that the OEM part number has been updated to 14 132 11-S. I want to have a new plug on hand should the need arise, and I could order online, but would prefer to buy local. What I'd like to know is, since local doesn't stock Kohler, which other plugs will work on my mower? I've tried cross referencing on a few websites, but I get conflicting results. Best I can determine, a Champion RA8HC should work, but I'd like to be certain before I buy.
