Default RE: Help needed with pump on OS FS 120
On the FS-120 Surpass I And II engines, the nipples are this:

"IN"---From fuel tank to pump.
"OUT"---From pump to carburetor
"R"---Return line back to tank

Here's how to adjust your carburetor:

For the instructions, you can send an email to the address listed below. The FS-120 Surpass I has a large brass screw in the center of the pump. The FS-120 Surpass II has no screw on the pump, but does have a long velocity stack on the carburetor. The carbs are different, so the instructions are different. If you email for the instructions, please let us know which engine you have.
