Question about Plumbing
Start with 1.5 turns on the low speed screw and 1.5 turns on the high speed screw. You can fine tune from this setting.

Testimonial: "Thank you for your quick response. One question which screw is which? One screw is smaller than the other for fine tuning?"
Workshop Manual for my a Husky 357XP/359 says (willing to wager yours is similar):
The Husky workshop manual on Appendix A (USA) says "H" 3/4 turn CCW from lightly seated. "L" 1.5 turns CCW from lightly seated.
Page 36 (every other nation on earth) 1 turn CCW from lightly seated for both the "H & L" needles.
There is no recommended initial "T" setting. (from manual) "The idling speed is correctly set when the engine runs smoothly in all positions and there is a clear margin to the speed at which the chain starts to move".
These are initial settings and the saw needs to be adjusted for performance. Start with a clean air filter and a fresh fuel mix @ 50:1 per Husky (1 gallon of premium fuel to 2.6 ounces of quality 2-cycle oil).
This explains performance carburetor adjustment better than I can:
Carburetor Adjustment by Madsens.com
CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.
There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too. HTH
