Well, motor's in, took a bit of jiggling and adjusting.. Installed the top stuff 3 times before I got it all right. However, detected some or other problem with these heads, so, not sure for now where we stand, but there's an issue. Await technical input from my super mechanic.
Update. problem not with Machining specialist, but with installer.. I just hadn't set the Carb's linkage correctly, because the heads were now in a different position to them being removed, slight machining), so I had to re-set up the linkages, as they were all out by a few mm's.. What a difference. Stripped them down, and remounted them, and all of a sudden, motor idle stabalized, and ran smooth as butter.
