request a lesson on engine timing Options

[type47]

I'd like to know on what parameters does the timing of an engine depend: induction? cam? I am resurrecting a 2L with a carb cam and installing a CIS basic system. We started the engine at the ECC in Oct and am progressing very slowly. I think the engine has an 009 dizzy (engine is still at ECC site so can't check now); at least it has a non-vacuum advance dizzy. I have a 2L D-Jet dizzy ready to install and that will probably be one of the next steps. When we started the engine, it did not sound smooth running but it started and that was the intent at the time,

but there could be other things that caused that. My question is really to what specs do I time the engine; 27 degrees @ 3500 rpm like a D-Jet?

The CIS fuel distributor in the video is from an early (83-84) GTI. At the time of the video, which was taken at the ECC in Oct, I just wanted to see if the system would run the engine so no AAR or cold start components were operational. The 83-84 GTI fuel distributor has an electrically controlled frequency valve (lambda control) and electronic controls (ECU in particular) are something I was trying to avoid so the current installation uses a fuel distributor from a circa 79 Rabbit which does not have the freq valve. Having said I am trying to avoid electronic controls, I will have the cold start items (cold start valve and AAR) that will be installed in the final configuration. I'll have to learn about the electrical controls for those but in warmer weather, the cold start probably wouldn't trigger and the AAR can also operate off engine temp. I'll check valve adjustment and for vacuum leaks before engine installation. I did use new intake runner to phlenum hoses and the PVC piping was glued so there "shouldn't" be any vacuum leaks in the video. I'm just concerned with the dizzy, which I think is an 009 and if D-Jet timing specs should be used. Thanks ...
