[TR] ZS XD 175 carbs needle adjustment

[James Henningsen]

Should be a locking screw on the side of the piston.  Take suction done off pull out piston and loosen screw for adjusting needle.  Put piston back in and dome on then can adjust.  Jim Henningsen

I was attempting to adjust the needle using a carb adjustment tool that locks the upper part and passes the wrench through to the adjustment.  The wrench will seat in the adjuster, but will not move either way.  I did not think that these had locking screws to prevent any change.  I was reluctant to force the needle and wanted to see if there is something I am missing here.
