ok,, I don't have manual, so, there are two black turn knobs on the side of carb. one i know is the idle,,what is the other black turn knob??? '09 foreman 4x4 es

 

[Fourtrax]

Not sure if its the same on a Foreman, but on the 300 one is the idle and one is actually a PUSH button primer for the carb. I've NEVER had to use mine so not sure why its needed.

 

[tng6664]

makes sense "four" as you can push it like a plunger

 

[Fourtrax]

Yeah if you can push it like a plunger thats exactly what it is.

 

[submarine 300]

Yep I agree.

 

[Helmut]

Yeah, that's what it is, the primer pump.
