Walbro WJ6A carb for Stihl 064

[Rodbolt]

Does anybody know what the inlet needle popoff pressure should be on a Walbro WJ6A carb and also what the inlet needle lever adjustment is suppose to be?
I've searched for a manual but can only find for newer carbs.
Thanks

pop-off pressure is almost irrelevant. Needle should hold 10psi indefinitely at the fuel inlet.

Happy New Year!...
