Did
you ever change a clutch disk in a car and then after drive-shafts and
all was back together the pedal didn't go in all the way in and the clutch
didn't disengage?
Taking it all apart again and measuring the new clutch disk thickness
to no avail and re-assembling it --- same problem, pedal moves half way
and hits stop.
going down the list of options I eventually checked what pedal I had my
foot on, well I did only sit in the car with one but cheek - I had pressed
twice in a row the brake pedal - so call me anytime you need some fine
technical advise ;-)

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)
