Timing Belt: how loose is too loose?

[dclose@tcadvertising.com]

Hello all,

I've been following several listers experiences with t-belt noises and am
still experiencing the same thing. While true that loosening the tension
makes the noise go away, how loose can the belt be before a problem can
occur?

I can twist my belt over 90 degrees now and still have a noise slightly
above idle. (all new components) I'm afraid to loosen it any more in fear
of jumping teeth. Any BTDTs?

What is the farthest twisting (in approx. degrees) anyone has gotten away
with and not had a problem? TIA.
