I have been fighting the D jet slow idle on my 1971 1.7. Have checked and rechecked everything. Bought a smoke machine. Bought a new timing light with advance. All new ignition parts. Checked MPS. Checked all sensors with ohm meter. Disassembled and cleaned Distributor. Good compression. So started disconnecting things. When i disconnected and plugged the vacuum retard I was able to adjust a 900 rpm idle with the (finally effective after removing vacuum retard) idle air bleed. So I did a search for "914 vacuum retard" and this link came up. Read the last post. Exactly fits my symptoms. I'm going to try what he describes tomorrow and see what happens. But I'm pretty sure I'm on the right track finally. Thoughts?

Sorry wasn't clear. Haven't driven it yet. I need to check for detonation still but don't really expect any. With the vacuum retard attached I'm not surprised the idle sucks. I haven't figured out how to accurately measure retard with my timing light yet, but just by counting fins and comparing to the distance between the TDC and 27 degree advance marks I'd say my timing when vacuum retard is hooked up is about 15 degrees ATDC.
