while in college I installed a Buick v-6 in my willys m-38 jeep. one day I had the bright idea of putting it in low transfer, first gear, and driving it back into the garage simply using the starter. I forgot I had a rod disconnected and it drove the rod clear thru the block. duh!

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)
