I've just moved and have to make new filters. Have been thoroughly enjoying my sound system but have to get back into it in order to get some decent correction. More, so I have to remember how to do things.

In a simple stereo measurement what should the delay be between left and right?
 
If the microphone is properly centered, the delay difference should be inside 1-2 ms.
Ok, great thanks.

And can you remind me if this is a normal impulse response. The red starts inverted to the blue... Is it normal that right and left are not on top of each other?

This looks like one of the speakers actually is inverted. You can try to flip left and right out of the sound card. If the two speakers switch behavior something is wrong here … glitches in the Audio stream.

Okay i think the polarity was off, thanks.

But the fact that they do not overlap each other, I mean literally sitting on top of each other is that okay?
 
The first is higher than the second. Which is typical since the first is closer. But you need to find out whether the measured delay matches the difference in distance. 34 cm equals 1 ms…
