VM26 flange mount type pilot fuel screw adjuster

[Goob]

Hello all,

I got a pilot fuel screw "adjuster" that has a little knob on it so you can easily change the screw position. This is for the VM26 flange mount carb that is on my Orion RXB150.

This comes with one really small washer and one really small O-ring. Based on the photos in the following URL, it looks like from the pointy end it is spring, O-ring, washer. Is that right?

Will it be obvious when I take the stock screw out?

Thanks for any help....
