FCR Tuning - Adjusting the air screw to the appropriate setting after changing the slow jet - 2023-08-13...
The position of the air screw has been adjusted to slightly less than 0.30 minutjes return. The pilot jet has been changed from 45 to 48. This air screw setting in summer may not be ideal for winter, as it would likely need to be adjusted (tightened) during colder months.
