My car has the stinckys!! I have the 400 engine with electronic ignition. Since I got it I have struggled with smelly exhaust. I did read the posts and pretty sure my tailpipe is stock angle and my windows are closed. I did changed the valve on the air pump and it seemed to run smoother and helped the smell go away a little. I got some good advice here about my 68 Newport 383 that included the use of a vacuum gauge but I didn't get one. Well, I got a gauge and want to do the best I can to tune this car. Yesterday, ,I finally spent a little time adjusting the timing to about 7 degrees but had to use a 1/4 inch socket with a u-joint and at some point it interferes with the vacuum advance when I turn it...bought a set of claw wrenches and gonna give it another shot today... Do I disconnect the vacuum advance and when? I am a bit confused: it seems there are 3 things that affect the idle speed - the idle screw, the mixture screws and the timing... Soooo....in what order do I adjust these settings? I have read that when setting timing, I should connect my vacuum gauge to manifold vacuum and advance the timing until the vacuum doesn't rise. Is this the same for the other adjustments? I did buy a dwell and tach meter but the RPM readings don't seem to make sense. I love driving the wagon and it get's a lot of attention (I am not an attention hound..lol) but it is a bit embarrassing to be so stinky.
