Just came in for a snack from working on our 3V Triton. Doing the spark plugs after 90K miles. So far I've got 3 Autolite HT-15's out without breaking any. The double dose of Gumout Regane (supposedly with PEA) for the last tank may have helped.
It may not make any difference but I'm doing these cold and filling the well with carb cleaner, breaking them loose a 1/8th or 1/4 turn and letting them set a bit, then turning them in and out with a light touch until they start coming out easy.
