Well, having to do a bunch of cross country flying moving grandchildren
around, 20 hours over two weeks, means I had to put in 100LL at
whatever backwater airport I happened to be at, instead of the cheap
nasty mogas I usually burn... Of course, starting up on a remote
airstrip mean't finding a fouled plug from that leaded crap they call
avgas... No tools with me because I needed every pound of gross to
move overstuffed suitcases and five bodies... No mechanic within miles
and no reasonable way to find one... Luckily I was alone at that
point... After two attempts to burn the plug free failed, I sat there
and thought it through... Two engines... 8 cylinders... 15 working
plugs... And a light load... I opted to move the plane first and fix it
later... The take off was uneventful and the plug actually cleared
about 5 minutes later...

Burning mogas for years means I have basically forgotten what it's like
to have a fouled plug and so I sit there on the ramp quivering like a
student pilot with his first failed runup... The reminder was not
enjoyable... I'm going to order a new set of plugs as these have 500
hours and my mechanic has been grumbling... I'm toying with the idea of
fine wire plugs, but they are 3 times the cost of massive electrodes...
Gotta make a decision... Jeez I hate that....
