Cam setup advice ?

The blocks which attach to the tube are bore aligned, much like a piston rod, or a ferret transmission mount. They must be kept together and in the same directions that they were made. If it is your blocks that actually moved away, then perhaps that is your problem.

If it was the adjusting bolts turning, then they just have to be tighter. And yes, that inner one is a bitch to get to. You almost need to pull the rad and the oil cooler to do it properly. I would do what you have to do to tighten that one up first, then tighten the second one.

You have my sympathies in all this. Doing those adjustments in a carrier that is already put together is a much younger man's game. 15 years ago I was doing one when I was still in the service (it was a museum piece, I am not that old) and I had to get one of the young female gunners to come over and reach in to install the bolts on that inner one. My hands were just too large.

I note the British army does not use females in the front line jobs. The are irreplaceable for this kind of work.
