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.    |

Advance ramp up seems a little slow to me, especially for a 1.7, you want it all in by 3000 RPM
Factory max advance is 27 degrees, Jake says he usually sees best power with 28 |
