I'm going to try the water trick this upcoming spring. Never heard of it before and would have been a little leary if someone mentioned it to me, but since you all live by it I'm all for it.

That being said, the last time mine was running so-so, I just assumed that it was due to an old engine and a unproperly tuned carb... till... I was on Woodward in Detroit and I came acrosss a 66 Pontiac LeMans and was challenged to a duel. After going full throttle a couple of times I noticed how much better it began to run.

So the trusty run-it-hard technique works well.
