Ah the classic "Quick Run Blues"!

From what I have heard, this is a real no no ... start it up, run it for just a moment or two, then shut it down. Why exactly I am not sure, but seems to me that it might have something to do with the (lack of) rebound of the seals, when they get hot quick and expand ... but the housing never expands to "let them loose" so to speak.

Result? they get stuck in the retracted position.

Solution? Squirt about a tablespoon of automatic transmission fluid (trust me, it works) ... into each leading plug hole. Spin it a bit. Wait 10 or 15 min. Spin it a bit more. Install new plugs.

Let it warm up before you shut it down and all should be well.
