I decided to get back to a project I started 2 1/2 years ago. I have a spark plug tester out at the hangar that went TU. The problem was that all the plastic pressure tubing rotted and needed replacing. I got the tubing and started to work on it then lost interest. The issue with the bad spark plug on the raffle plane got me moving again. We had been testing resistance. The culprit plug seemed OK resistance wise, but not OK on the tester at the museum. The tester at the museum was right.

So I decided to proceed with the resurrection. One thing I do when taking things apart is to snap some photos as I go so I have a reference. I went back into my Lightroom database and found the requisite photos and uploaded them to my iPhone. Now I have a ready visual reference for the project at hand.
