MessageOK, Guys. Here's another chance for your valued remote diagnosis
input.

After 2 months hiatus my engine now starts reliably and runs
consistently....just very very badly. In all the time I've had the engine
running, with various problems of mixture and tuning it has NEVER run this
rough. It shakes, and max rpm is about 2100. Each plug seems to have a good
spark but today I installed new plugs anyway and checked the voltage on all
coils and injectors. It runs exactly the same as it did yesterday. The plugs
are black and the engine blows a bit of blue smoke.

It IS running rich, so I tried changing the overall range with mode 3. As I
lowered the mixture with 7 or 8 pushes the rpm came up a bit, then started
to slow down again. At the best rpm the EC2 is showing slightly higher than
center on the mixture. I tried switching off either set of coils and felt a
degradation with either off. Disabling secondary injectors killed the
engine. Primaries didn't make much difference. I checked compression. 105#
on each rotor.

My next thought is to check that cold start is operating properly, but I'm
pretty sure it is because the engine slowed down when I tried switching it
on.

I spoke with Tracy and he suspects fuel, possibly a bad connection in the
injector wiring, so tomorrow I'll rewire the entire injector circuit if
necessary.

I'm so glad Rusty still doesn't have power. I'm not in any mood for jokes :(

Thoughts anyone???
