hello I have problems with the regulator of a bsa r10 mk2

[alcuerna]

bsa r10 mk2 .... I need help please someone could tell me in what position the choke screw goes to the bottom of the regulator. I do not know if it is completely closed how to calibrate its opening. I leave the photo of the screw

honestly i would dump the bsa regulator and get a huma replacement. changing it out was a breeze and the gun worked better. JMHO. 

unfortunately i do not know the answer to your question , good luck with it though.

I second the huma reg.

Go to YouTube and check out XTXair. They have a lot of BSA R10 disassembly and tuning videos.
