    "Not a big deal. Just be sure the floats don't go down too far and jamb in hte down position. Once the carb is assembled and gas appears, the float drop is no longer an issue.

    Thanks Jeff. My issue is the accelerator pump only works for one ot two squirts then the fuel level is too low.

    And when I put the engine in gear it sputters and dies.

    I am thinking the floats sit too low and are closing off the fuel supply too early.

    The drop on them right now is about one and half inches.

    I think it should be closer to three quarters to one inch.
