    I can only say this because I've done it a few time.

    That piston can go into the carb 360 degrees of rotation
    and only one place that's correct.

    I bet if you just unscrew the cap and rotate that piston as you push/pull, it will DROP in when it's right.

    There's an inclined ramp on one spot that the idle screw kinda pushes up on.
    and that's your reference.

    I've also popped the 'w' clip that holds the needle down INside the piston.

    Then the main needle is free floating and settles wherever it wants.

    Or something is mounted crooked and you have a vacuum leak.
    Did your 'o' ring happen to fall off?

    pls keep us posted.
    Sounds like a pretty common prob with ez answers.

    Re-check your work bud, sounds like something is either still dirty or not assembled correctly..
