Well, I feel like my Darmah may have been assembled in Germany, then, with all four openers within 0.30 mm… I an halfway through with the closers. Got to at 0.01 by just replacing the closer by a 1 size up bigger one (measured by difference - shim turning through the entire cam shaft revolution), so that’s lucky. I am now grinding off a couple 1/100 one rhe remaining two to try and get the same result. When that’s done, I will be able to properly tackle the openers. Stay tuned ! Edit: Look what the postman brought me today!!!
Ooops got that wrong, it was the openers that were 3.48, 2.27, 3.31 & 4.03. The closers are 5.94, 7.23, 5.61 & 4.88 - which is just as random
A lot of the valve shim difference(s) can be introduced by having the seats replaced/ground. There's a lot of info in that book but what I found most useful were the pictures & technical dimension specs. The wiring diagram proved a godsend for me when doing the rewire.
