how should is sound and feel

NCwoods:
Hi I just got my 500 running. I am using an 38mm airstriker and a Rad valve.

I have a JD needle in the middle position and 168 main. I forgot my pilot. The quesiton I have is should this engine feel and sound chrisp? I had a few other 250 two strokes and they sound clean and chrisp. This sounds soft. Is it from the larger displacement? It feels good and very powerful. It does not feel weak at all, just doesn't sound tingy like I am used to. Maybe nothing.

Thoughts?

And As I Found Out, The Rattle You Hear In The Video Is Normal. EXhaust Valve Rattle.
