Who has an HRC A needle from an MC21 kit and an accurate micrometer or verniers? And can measure it for me?
It's the closed throttle part of the needle I want to know the diameter of. Widest "useable" part of the needle.
I have
J81E : 2.80mm (Standard non adjustable MC21)
J06C : 2.72mm
J06D : 2.73mm
I just ordered two new HRC A needles, hoping they are between 2.73 and 2.8mm.
