timing with Weber's

If that's true (and I don't doubt you for a minute), then that small amount doesn't really matter. I never thought about it, but I'd bet I would lose a few degrees if I secured the advance weights with the engine off, and then checked it at idle.

That would still be included in the base timing, and so is not really advancing. I checked mine, and I don't see any true advance over base timing until the tach hits about 1,200'ish. Up until then, the timing stays right where I set it at idle (850 rpm's).
