Question if anyone is running this combination. I bought both from DWR and they have told me I can use the intake manifold vacuum port to run the vacuum advance on the CSI distributor. That doesn’t seem right to me as the SU carb vacuum port used for the factory vacuum advance behaves differently to manifold (post throttle) vacuum. Not sure though if the electronicsnon the CSI distributor are just smart enough to avoid the vacuum signal at idle. Is anyone using this combination?

Is there any harm in running the vacuum distributor with the advance port capped off? That way I can try it and it’ll it gives wonky behavior at idle I can just cap it. Otherwise I have to return ship the distributor to DWR in the UK and get a non vacuum one.

Thanks for any advice you have. CSI website doesn’t have a lot of information. I suppose a call to them will be my next move.

Just don't connect the vacuum advance up. My BJ8 with triple webers has never run a vacuum advance.

Thanks for the response back. I will plan to just plug it.
