    Carburetor CRF 150RB help

    Hi!

    I'm failing to figure out the purpose of this adjustment screw on my CRF 150 RB 2009, as shown in attachment. Sitting right side above accelerator pump house.

    Anyone know? And tips for using it?

    Thanks a lot

    Bit hard to tell from picture, but if it is screwing into the float bowl it would be a drain screw.
    Don't want fuel going stale and clogging jets.

    It starts,it runs,it gets to where all CRFs can get to without the valve or valve plate dramas
