Here I'll pull the old plugs and test them. I've also acquired 3 new plugs to replace the older looking spark plugs on the bottom side of our Lycoming. 0:00 - The Plan 1:52 - Disassembly & Visual Inspection 6:13 - Attempting the multimeter 13:28 - Frustration 17:00 - Put It Back Together 20:00 - Test It 22:08 - Debrief #mytimetofly #generalaviation #mooney https://www.bonfire.com/dashboard/ove...
