Cam Friction Gear Adjustment
 

So, I finally got the heads on, and torqued. Now I'm putting the cams back in.

I own the manual, and I know it says to "use a screwdriver to adjust the cams so the lobes don't lift the HLA's"

I CANNOT get the friction gear to budge, in either direction. It WILL NOT move.

What am I doing wrong, or how else can I move it?
