[ARCSinAK]

Hi John-

Thank for your advice. The original air box had a leak, I had a spare 76 CIS system that came from a good running 2.7. Installed it with all new seals, new injectors. After installing I had the same issues, cold start and cutting out under full throttle I did before. I was so frustrated. It would only start if I bumped the sensor plate, after I manually idled it to temperature it ran pretty smooth and strong on the first couple of drives but then developed the same issue of cutting out under full throttle I had before the CIS change. I attributed that to ignition/lack of CDI since I had changed the entire CIS system. I also changed out the thermo switch and used the 76's 7th injector harness as the 74 had a different connector hoping to cure the cold start issue but no dice. Decided to install the MSD 6AL box to rule out ignition. I installed the MSD and it started but it was not right. It ran but motor seemed out of balance. I noticed the sensor for magnet was loose on the Pertronix, removed distributor to address that issue and that's were things went south with the timing. Had a couple of radical backfires, 44 magnum kind, think I was 180 degrees off once ETC. Now I only get an occasional burp/pop no start. I am aware that bumping the sensor plate to start is not all that wise given the uncontrolled fuel and mixture problems. Hopefully the mufflers in one piece and the 76 air box is still intact. Had to walk away yesterday. Is there any other way to determine TDC on number 1 with out removing the valve cover?


Flat 6-
Crank Pin indicator? Hole in the pulley? The pin that holds the distributor? When I have the distributor adjusted to the original position, aprox center, the rotor dot seems to be off a little in each direction depending on what tooth I'm on. Thats what I found confusing.
These are the only double notches on the pulley, also no Z1 engraving. Does that rule out that the marks on the left could be 30-35 BTDC ? Could the motor have run at all if I had it 35 degrees out? I have timed it before using the marks in the center image and when I rev (advance) the motor the timing light view on the pulley moves to the right of the two center marks. The only other marks on this pulley are singles at apron 90 degrees. I searched a bunch "pulley marking threads" and have yet to see a diagram of a pulley with the marking mine has???

I sure appreciate you patience with my remedial questions.
