C3 Smoke
My 79 let's out a bellow of smoke white/blue ish when I'm sitting at a stop light idling and I take off (4 speed) It just started doing this, no smoke on start up ( did valve seals last year), flying down the road or wing it up between gears and shifting. It's not antifreeze. Not the PVC or EGR. Vacuum is good. Is my Rochester card need adjustment? Loading up with fuel on idle? Bad gas? I just dumped some carb cleaner and sea foam with fresh gas. We shall see? Carb was rebuilt multiple times over the years. Otherwise car idles fine, and runs and starts good. Please help! Here's a short video, it may not open, Sorry.
