i will count my setting on the needles to let you know tomorrow, i dont know off hand but 2 1/2 out on the high needle is always a good staring point for any nitro but the low needles are very different from brand to brand and it sounds like your low end needle needs some adjustment.

not sure the temp but blue smoke at low speed

high speed needle is too lean. i've been there with my vx18...i thought it was an air leak
