  • Please help me with my doubts on distributor timing

    Well,

    I have put it all together and am just about ready to turn it over. But I have my doubts about my distributor and timing prior to cranking it and trying to start it. I would hate to destroy all the work I have done. Please chime in and let me know if I am just being paranoid.

    Some background so you can follow my process here and tell me if I am missing something critical.

    It's a 76 TR6
    Jeff at advanced distributor rebuilt the distributor and removed the retard unit. He suggests I set the time at 14 BTD.
    Engine completely rebuild from the ground up. All new everything!
    Installed a new cam with a 270 degree duration.

    1. Pulley set to 0 TDC.
    2. Valve covered pulled off and validated number 1 cylinder is ready to fire. Push rods are loose meaning no valve compression on Nr 1.
    3. Primed engine. Good oil pressure.
    4. Distributor gear installed with appropriate offset and pointing like in the manual. approx 2:40 on a clock
    5. Distributor installed, with rotor pointing to Nr 1.


    Set my static timing with a test lamp ...

    1. Rotated engine counter clockwise from TDC and set pulley to12 BTDC.
    2. pulled wire off coil
    3. hooked up wire to negative on test lamp
    4. hooked up test lamp positive to battery
    5. rotated distributor counter clock wise so light would go on
    6. rotated clock wise until light went off. ( a few times for valiodation )
    7. locked distributor.

    Ready to rock and roll but would love some feedback!

    pretty straight forward but I am NOT happy with the way the distributor is sitting now and the TIGHT angle of the tach cable. based on the above, does it look like I missed anything? Am i being overcautious here? See the photos below so you can see what I mean. Also, I need a longer tach cable if this turns out to be correct.










    Thanks

    This is the factory set position of the distributor.

      You're fine. Go ahead and start the damn thing. Looks good BTW.

        I believe you are off a tooth on the distributor drive gear. Will it run? If everything else is right it will. Will it break the tach cable in the future? Maybe.

          Mine looks pretty much identical to your pics and its been that way for a long long time.

          Never thought it looked right.

          Never had the tach cable fail.

          Car has always run pretty well.

          I say go for it.

            Everything looks great, nice job. I had same problem with my tach cable, I rotated my plug wires one position on the distributor cap and corresponding plug positions, gave me plenty of play with the cable. John

              Thanks. Makes me feel a little better. I may just turn the drive gear one notch. I read on another forum that the Bently manual indicates wrong position and I am off by 1 tooth.

                  Jtorral,
                  you are off by one or two notches.
                  Rotate and look at your distrubutor finger pointing at 7 or 8 o’clock position with 1. @ TDC. Reposition wires accordingly.

                    Truth is I'm considering doing the same thing even though its been the way it is for a long time. My tach cable is so tight that it sometimes threatens to tangle with the rubber steering column joint.

                      That would probably be because your tach cable is misrouted.

                        Wow! that's really interesting...I had no idea.

                        Definitely going to have to fix that. 20+ years since I put this thing together and all that time its been wrong.
