got a used savage XL and while tuning it i mistakenly adjusted the mid range screw. I had originally turned it flush with carb body and then adjusted from their. The top end is running perfect shifting properly and not over heating. The only issue i have is it has a slight bog on takeoff from a dead start. I'm assuming i just need to adjust the low speed needle a bit. Is their a factory setting for the mid range screw or should i leave it now since the mid and top end are good?
