I’m not sure what happened. I was following the instructions to check the sparkplug gap. This sure seemed like a lot of BS just to checks plug gaps, but the Company service manual said so. It must be the truth.
It was about the time I noticed the cat sitting in the doorway laughing at me, that I also noticed the instructions were for checking piston gaps, not plug gaps. Stupid me, guess the cat got me. She changed the page while I wasn’t looking. That’s OK. When she gets hungry I’ll give her the instructions for the coffee pot instead of the can opener.
