First is this an FCR or CV carb?

2nd, Does anyone know of one of the adjustable fuel mixture screws that will work?

 

[Here 2 help]

The carb is neither an FCR or CV - it is a Keihin QB11A-A used on 2005 to 2009 TRX400EX's. Not sure about the fuel mixture screw. The stock screw (part # 16016-HN1-A41) was used on 05-09 and 2012 models.
