The handle is definitely moving the mechanism, and the cams are going about half way into the keeps. I’ll see how it goes now I have adjusted the cams. Appreciate your thoughts.
Half way down the slots should be ideal.
There's probably +,-1mm adjustment by rotating the cam. If it had been adjusted fully loose, you can sometimes get a gap.
