Does anyone know where I might find a vacuum diagram for a 73 Valiant? Searched the board but the links were expired. The old Valiant has been sitting for a few years unloved. My oldest son just got a license and the Larry (the 73 Valiant) is looking real good to him. Idles like a tractor......gonna change out the carb and the normal tune -up stuff.

Any help will be greatly appreciated

Thanks

David

Do you have emmisons testing in your area? If so the only thing I would bother keeping is the EVAP canister (goes to carb bowl vent) and the vacuum advance line that goes directly to the distributor, nothing in between.

If it idles bad, I would do a valve adjustment. Use Autolite 985 plugs or NGK ZFR5N plugs gapped at .035 without the washers. I am sure someone on here has a vacuum diagram.
