Good input, Harold :-) If you manage to get a cam off by a tooth, the engine runs like a bag of nails - got the T shirt on that one! I think Nick has now manually timed up the cams with a dial gauge so the process is very different than following the book The early Renault engines have a single fuel inlet on each rail and quickly moved to twin pressure regs and twin inlets so there may be a pressure differential along the rail - but I suspect the symptoms of that would be less obvious than these. Nick: remind me, have you tried running the cams at 110 degrees inlet full lift? Mate if you get really stuck, I can supply a pair of cams from a Z7U turbo engine which you can time up by the book. For anyone's interest, we have two complete Z7U 2458cc turbo engines ready to go. I've already hybridised a third into a DeLorean with an Island Twin Turbo.
