Hi Mehdi
Thanks for contacting the Answer Army to post your questions.
Answers: 1) The rule of thumb is for the unit to run out of fuel and bar oil at the same time. As long as you are using bar oil and not motor oil you cant really have too much. If your oil tank is getting empty before your fuel tank you may want to adjust it down just a bit. And yes the adjustment screw only turns 3/4 the way around. 2) The break-in period is roughly 4 to 5 tanks of fuel. By then your rings and everything should be completely seated and at optimal running performance.
Thanks again from the Husqvarna Technical Services Team.
