You don't mean spring, washer, o ring?

In order they go on: Spring, washer, o-ring.

spring,washer,o ring. that way o ring seals up against the seat and the washer stops the spring from chewing up the o ring as you turn the screw.

I agree with agemax. Spring, washer,oring.

picture is WRONG!

you want the Oring to seal against the carb body and the washer to protect the o ring from the spring and the spring prevents the screw from dropping out. .

spring onto mixture screw first
washer onto mixture screw next to the spring -
O-ring goes on last last. and it holds them on the mixture screw while you install the assy into carb body.

install until lightly fully seated. then come out 2 full turns and begin carb idle drop tuning from there. (bike will start easier if you do it that way. )

Hey Guys, need some help here. I have an 82 GS650 which according to manual uses Mikuni BS32 ss carburetors. I am looking for the air/fuel mixture screws that go on top front of each carburetor. I cannot seem to find the correct part number. I do see these screws for GS750 and GS1100 but nothing for the 650. Any of you would happen to know what would be the part number or where I can purchase these screws?

Thanks All, good and safe riding!

Did you ever find the part number for that air fuel mixture screw? I need one or a set for my GS1100 and can't find the part number anywhere
