Where can I find a Quadrajet vaccum diagram for an 85 k10 305 ? I think I want to hook my smog pump and other emissions back together. Any suggestions ? Truck idles fine and then the idle speeds up and slows down for about 5 minutes and then it levels out for a while.
How much vacumm adance should my carb be pulling ? I'm not sure if the bell on the distributor is bad or if the carb is not pulling enough vaccum . I know the bell is only a 6 dollar try it and see but I like to learn...
I learned this time around again...My vaccum advance hose was connected to the wrong vaccum port on the carb....ouch lots of lost hair...the ones that didn't turn lose turned grey..
