Cleaning & gapping upper spark plugs

8/14/16, Tach: 93.9, Hobbs 105.0

The engine seemed a little easier to start so I decided to also clean and gap the top spark plugs. Once again, all measured > 0.022 on the feeler gauge. I reset all 4 to 0.016.

I also measured the spark plug resistance: #1: 730 ohms, #2 680 ohms, #3 710 ohms, #4 760 ohms. This seems good. The spark plugs that are currently installed top/bottom are the original (came with engine) Champion REM38E (massive electrode). I used new copper gaskets on each.
