    That part number is for the lower carb assembly so the uppers are 0439188 those are for the 200. For the 225/250 uppers are 0439509 and 0439510 for the lower. Carb body for the 200 is 0437323 (mid bore) uses orifice numbers #27 0317474 and 67D 0319534..
    225 uses carb assembly numbers 0439509 upper and 0439510 lower carb body number 0437326 Orifice size #30 0317473 and 72D 0328546.
