Tonight my only tasks remaining on my conditional annual inspection pertained to the engine run. The engine started quicker than I ever have experienced - like on the first 1/2 turn of the prop. I was stoked, all my work on the mags and timing must of been successful. Not to gleam in my brilliance too long, the first test I performed was a quick mag test, which quickly rained on my parade - the engine died when running on the Slick mag. Tail between my legs I pulled the airplane back into the hangar. I pulled the plug on #1 and set it to 25 degrees BTDC. The timing buzz box showed all was timed correctly. I then took the harness off of the mag and checked the timing - sure enough the internal timing checked out too. I yanked the magneto and inspected the internals in case I installed the gear incorrectly. Everything looked fine to my disappointment. I slapped the mag back together, reinstalled and attempted another start. Nothing. Still didn't want to run on the mag. Was it dead? How could it be after I inspected it?! I was pretty disappointed with myself. I had another 4371 mag at home as a backup that I could use to eliminate the mag. I stepped back and looked over everything that could of been wrong - and then it hit me - I wasn't timing off of #1, but instead the #2 cylinder......shit! I re-timed the mag to #1, and guess what? She fired right up! This made me think of the definition of insanity - doing the same thing over and over again and expecting different results!
