I have an old 91 surpass that I bought new in 1990 and I was wondering what the mixture needle settings is. This is the 91 surpass it has a choke on it it IS NOT the surpass 2

There really isn't a "factory" setting. Just open the high-speed needle valve about 2-1/2 turns out from closed and go from there.

I wasn't talking about the high speed needle adjustment, the manaul calls it the mixture adjustment screw but most people call it the low speed needle or idle needle and on the surpass 2 the factory setting is 2 turns from the bottom but the surpass 2 has a differnt carb than the older surpass

According to the instructions, you close the throttle, and gently turn the idle mixture screw clockwise until it stops. Then turn it back out 2-1/2 turns for the non-pumped engine, and 2 turns for the pumped engine.
