1968 200ci Distributor. I need help with the connections

[TheDude]

-1968 200ci engine, stock distributor, Pertronix ignition

I do not have a 1968 shop manual to refer to so I am pretty lost when it comes to the distributor. There are two places where hoses connect to on the vaccum diaphram. I am not sure if I have the two hoses connected properly. At the farthest (at the end of the VD) connection I have the hose routed to a square block that screws into the intake log. At the other connection I have the hose routed to the (sorry I do not know the name) thing that screws into the water pump and has three hose connections (like the ones on the VD). I connected the hose to the attachment farthest from the threads.

Where are those two hoses supposed to go?

Thanks,

Justin

This is from a previous thread and links to a vacuum line diagram that Simon made.

The vacuum switch tee was used as another emission control device. It was used in conjunction with the dual vacuum advance canister on the distributor. While the engine was warming up, it sent full manifold vacuum to the retard side of the distributor canister. This retarded the spark advance resulting in higher combustion temperatures which had the effect of warming up the engine faster and burning some of the otherwise unburned hydrocarbons during the warm-up period. Once the engine coolant was warm, the vacuum switch closed off the manifold vacuum port signal at the tee, and very little or no vacuum was sent to the retard side of the vacuum canister. Simon posted a nice drawing of the vacuum tee hookup on this thread.

original configuration of 1968 IMCO emission connections for 170-200", auto transmission and/ or thermactor:

- PVS bottom outlet is connected to filter unit
- PVS center outlet is connected to rear of dual vacuum advance canister (green stripe on vac. line)
- PVS upper outlet is connected to a "T", which is connected to air bypass valve on one side and to intake manifold accessory outlet on the other side (red stripe on vac. line).

- front of dual vacuum advance canister is connected to timed vacuum port on carb

Doug, you are my new hero. The thread you linked to has the exact answer I was looking for. Thanks!

Very true, so I shall thank Simon as well. Still, you are the finder of the precious information.

Justin, if you don't have emissions inspection, just connect direct manifold vacuum to the end nipple on the can, & leave the connection which is the retard connecton open, do not connect a thing to it. The best would be to replace the dual can with just a single advance port canister. By not using the retard unless you have sniffer inspections you will get the best fuel miliage & part throttle performance. William
