Verve thanks for the heads up on replacing the regulator adjuster screw O rings. I have never had my reg apart but have an idea of it’s make up from Ernest’s video.
Now if I read you right the problem is the O rings can only be fitted from one end of the adjuster screw. Once the first O ring is fitted to the shaft it has to be moved over the first O ring groove then slipped along the screw shaft and into the second O ring groove. Then the second O ring is mounted on the adjuster screw shaft and rolled into the first groove. I assume the difficulty is when the first O ring is fitted and drops into the first groove the problem is getting this O ring out of the first groove again so it can be moved along the adjuster screw to the second O ring groove. Is that right?
If so, could you not temporarily “fill” the first O ring groove by wrapping sewing cotton around and around the shaft until the groove eventually fills, and is level with the shaft of the adjuster screw. Then mount the first O ring, roll it along over the groove filled with cotton and along the shaft of the adjuster screw where it is positioned in the second groove. Then unwrap the cotton from the first groove and mount the second O ring on the adjuster screw and roll it into the now vacant first O ring groove?
Just a thought.
