No 1085 has an external adjustment screw (excluding a Kirby Morgan). The screw on the late 1085 from the Conshelf 14 (not XIV) is a port plug screw that can be removed so that a screw driver (or special tool) can be inserted to the slotted screw of the poppet. The cover must still be removed so as to be able to put a wrench on the nylock nut unless you have the special tool.
The second stage poppet screw does not adjust IP. The IP is adjusted via the first stage (140+/-5 or 125 +/-5 for the Supreme). Of course the second stage must then be adjusted to that IP set for the first stage. Here is from the manual so I do not need to be almost sure nor do I make WAGs. Note the direct access afforded the screw driver to adjust the poppet on what is called the "newer version" in the SM. If you have the special tool it has a screw driver that slips through the nut driver.
