I just got my 1970's engine back in after procrastinating with finishing up this project. Engine came out to address RMS and trans fluid leaks and a bunch of other stuff. I installed a 123ignition distributor. Stock 1.7 djet. It started right up and seems to run well. Idle settles in at 900 once warm. I need to address the AAR as it does not work. I took it for a 30 mile drive yesterday.
I wanted to ask about the curve on the distributor. I haven't changed it. The distributor is the bluetooth version. Pics of the curve and dashboard during the drive. Any input on what might need changing? Engine runs so much better. It does have new injectors as well. The old ones were not able to be serviced and one was from a 2.0. That cylinder was fouling.    |

@jhynesrockmtn , it would be good to have some advance at idle if you can do so and have the idle speed you want. You'll have better throttle response coming off idle that way.
Also, I noticed on your 123 dashboard that voltage is ~12.5. It should at least 13.6 to 14.2 at idle. You might want to check on that. |

I did add some advance at idle and will continue to drive it and play around with the values. Idle settles in at a steady 900. So far really pleased with how it is running. I'll put some miles on and pull the plugs to see how they are doing. I'll check on the voltage. Thanks for pointing that out. |
