Thanks for the replies. I have put the stethoscope directly onto the timing cover as this was an early suspicion, but, nope, sounds good in there. May have to remove the cover and make a proper visual inspection to be sure, but for now, I don't think this is the cause.

I will also, definitely, reset the valve lash and take a close look at each one's action.

I wonder if the bracket is the thing. The mounts are soft and cracked from all the time sitting, so the engine does wobble some. I have been working on tuning the kjet (another lovely story) and taken the engine to some pretty rough idles to try and find the sweet spot. Perhaps the combination of a super rough idle, on old and decayed mounts has caused enough movement to crack the bracket? If the crack is not large and obvious (which it is not), how could I test for it?
