Hi

This may sound like a daft question and apologies if it has been covered before (couldn't find anything on this) but can anyone tell me where the connection for the vacuum advance pipe is on the HJG46W carbs please?

I have the 3-screw round tops from a 240Z but I cant find a connection anywhere.

Thanks

should be on the front carb at the back of the round top very close to the manifold mounting.
