Here's the current regulator for the Surpass II
Yes that is what my regulator looks like to me but mine is still attached so I am not seeing it completely... The slot on my regulator is just above the fuel in nipple and next to the main high end needle... so it sure looks like it is between the main needle and the fuel in side of the regulator... I will make a picture of it soon and post for your evaluation of what I am seeing... Thanks..
That is your mixture control needle. If you don't have a manual you can get one here.

Thanks for the help.... I have a copy of the manual and the discussion on the pressure regulator is not clear to me but now another question...... You are saying that the screw/slot is a mixture control needle? if so, how do I need to adjust? Does it work like the low end needle on the engine because that would be confusing... It does turn but since the engine runs great and I am only trying to understand the starting procedures for the pump... would it be advisable for me to not try any adjustment on the regulator? I believe from what has been said here is that this engine and pump may be an older 91FS/pump? Thanks
