I would open the low speed screw some also before running it again.

If the low speed screw is too lean it will effect the high speed to where it has almost no effect.

[ul]Needle setting sequence[*] peak high speed[*] close low speed 1/8 turn at a time and check transition from low to high[*] When the transition to high speed starts to deteriorate, open the low speed 1/8 turn at a time to recover the transition to high speed[*] After satisfaction, enrichen the high speed needle 3-4 clicks
