Hey guys, update on the thing.
It turned out that (pardon me for the lack of technical terms) the screw on top
of the intake valve of cylindre 9 was completely loose. Preventing it from firing.
After retightening and checking the spacing of the valve, everything runs smooth
again.
It got me a little flabergasted, I have NO IDEA how that thing came loose.
The more you know...

There are 4 cam lobes on the intake cam plate and 4 lobes on the exhaust c
am plate.=C2- You will need to adjust the valve 4 times because each time
you rotate the prop and open the same intake valve, a different cam lobe w
ill open the same intake valve.Dennis

Some very good advice from Dennis and George.
If you have not done this before you will find that in adjusting the EXHAUST
valve clearance it is necessary to rotate the engine to open the valve
enough to provide clearance for the special wrench to properly engage the
nut.
If adjustment is needed the process is "check, turn, loosen, return to TDC,
adjust, turn, tighten, return and re-check". It is a process that requires
the utmost attention to detail. Fortunately not required for the intake
valve!
The only engine I know of worse than this is the R1340 (Pratt & Whitney's
first engine) which has a "floating" cam ring and a valve adjusting
procedure from hell!
