Greetings,
The grand prize may go to
Bruce Turrentine, with points to Tracy also. I called Bruce today, and the
first comment out of his mouth was "are you sure you aren't way retarded on your
timing". Well, I didn't think so, but after careful measurement, I found
that my original measurement wasn't so careful.
Remember that during my
first runs, I though the timing was retarded, and manually advanced it
some. The engine seemed to run better, but after discussing this some, and
believing that I had set it correctly statically, I set it back and forgot about
it. Well, my static mark was 10 degrees off. That means I've been
running about 12 degrees BTDC, rather than the normal 22. Think this
will make a difference? Yep, me too.
I ran the engine briefly,
and found that everything has changed, and I'll have to re-tune the whole
thing. I haven't thought about it enough to explain it, but now I'm way
rich over the range that I can run without being tied down (about 20 inches
MAP). The mixture knob is close to fully CCW now. I never understood
how I could run Tracy's parameters and have the correct mixture, when my
injectors were so much larger. Now if it will just reduce the boost
at full throttle :-)
Rusty (I'm a
dumbass)
