Can you direct me to or provide the diagrams I need to re tube the vacuum correctly? Smog test tech told me I was missing two hoses for smog pump and carb was hooked up to vacuum wrong and didn't do the smog test. The Chilton book does not have a very good diagram for either 1976 carb or smog system and I don't know how to determine what the lines should connect to what ports. The carb is the Rochester Quadrajet 4MV on a 350 engine with HEI Distributor. Timing is set to 6 BTDC and it idles about 800 rpm until I disconnect the vacuum advance and plug it, then idle drops and it runs rougher. I need it to pass California smog. There is no emission sticker in the engine compartment that I can find. Any help or direction would be appreciated. Your site was recommended to me by my son in law who got help with his 68 Impala. Thanks
