Well N96PM
makes noise again. It's running like .hit, but it IS
running.
The (final)
starting problem was the secondary injector switch. I found low voltage at the
secondary injectors and traced it back to the switch - serves me right - it
was one of those mini radio shack switches. They're supposed to be rated for
10A, but the innards of these things are pitiful. I know because the switch
fell apart in my hand. Two big fat DPDT switches later and the engine fires up
right away. But I'm pretty sure its running on one rotor, and THAT one isn't
running well - very rich, I think. The engine shakes more than it ever has and
doesn't respond hardly at all to throttle changes. Just sits and burbles
at about 1600rpm.
So, I have a
bit more debugging to do, but at least it's a step
forward.
