I think I may have a timing issue with my 84 Westy. When reading the Bently
manual, I'm a little confused as to what RPM you set the timing at. From
what I can  make out it appears to set the timing at 2500rmp? Is this
correct? (I have had to set early 911's at 6000rmp, which was a lot of fun
to stand behind with this screaming motor). Trying to diagnose a wierd
problem. The van fires up and runs for about 3 to 5 minutes, and then
gradually misses and stalls completely and will not start, not even with
ether. When it cranks over it has that sound and feel like the timing is
off, but never fires at all. I usually have to wait until completely cold
before it will restart. I have tested the sensors, the air intake plate, the
deacceleration switch and the full throttle enrichment switch, and they test
good. Tested the hall unit for voltage and flicker, and it tested ok. The
injectors have new seals and do not drip. New plugs, cap, rotor and wires
(the correct wires). It seems like the timing drifts away, if that makes
sense. As soon as I can adapt my american fuel pressure tester to the german
test port, I will see what the fuel pressure is doing. Compression is ok,
not great, 120-125 when the car is warm.

Any suggestions would be greatl;y appreciated.
