In sorting out the hoses on a 74 2.0, I discovered that the vacuum advance has
two ports coming out of it (Top Side/Bottom Side), however my intake only has one vacuum port. It is currently hooked up with the line going to the top side port on the distributor, and the bottom side is open. Question is, should this be plugged, or does it need to be connected to vacuum, and if so where to hook it up? Based on the information I was able to find, it looks like I have a early 2.0 distributor, and a later 2.0 intake. Any issue here? Thanks! |

No 4 cylinder 914 came with a single vacuum uit. All had one for the advance, one for the retard. Some engines didn't use the advance side, ALL used the retard. Note the ports on the TB are different sizes, as are the ports on the vacuum can. The hoses, when used, are of corresponding sizes.
