Pat -

Howard's explanation of the theory of operation behind headlight adjustment is spot-on, but perhaps a picture from the parts book will help:



(Just click on the image for a larger view.)

The movable bucket (4.13026) has a pair of slotted tabs, each of which engages an adjusting screw (4.13002) - one at the top (for up/down) and one and the side (for left/right). If those screws aren't properly positioned in the corresponding slots, then you'll get no movement of the headlamp by turning the screws.

Also, I believe that those screws are threaded into the bottom of the larger bucket (4.1301), which is held in a fixed position, relative to the sheet metal of the front fender. Make sure the threads on those screws or in that fixed bucket haven't stripped out.

Then, if you look closely at the illustration of that fixed bucket, you should see a hooked, coiled spring, which is secured to the fixed bucket by a rivet at one end. The other end hooks onto a notch on the rim of the movable bucket. If this spring is not secured at each end, then turning the adjusting screws won't do anything, either.
