I have to disagree with that. Mine has been missing for 20 years. Come to think of it....so is my trunk seal, my door seals, and every other seal. I don't hardly have a seal in my car and I get no fumes....It's not a seal issue. Your engine is not running right. I can stand behind my car aand not smell exhaust, unless I put my face right in front of (or behind) the pipes.

Actually, I haven't washed my car in more than 5 years. It currently only has a light coat of primer on it to prevent rust. There isn't much of need to wash a car out this way either...it don't rain or get dirty much.

the holley has one on each side of the front fuel bowl. start with closing them snug (don't tighten them as they're needles),m then reopen by one and a half turns. both of them
always make sure to turn both the same if you decide to open one side by quarter turn do the same with the other
what you want is the highest manifold vacuum in the leanest idle screw position.
if you don't have a vacuum gauge you can use a rpm meter. highest rpm for leanest setting.
check the manuals for holley or edelbrock. all info in there

I am new to this forum. I just signed up because I have this exact same problem and have been fighting it for 6 years. I have never seen a post on a forum that is this issue. If I keep my windows up, it is not so bad if not at all, but if I roll them down or open any vents then it smells really bad. last year when I tried to pass emissions, it was 4x the limit of hydrocarbons. I know that it is running super rich, but cannot find where to lean it out that much. I have an MSD ignition and have not changed the advance springs in the distributor. This past weekend I pulled my entire fuel system. cleaned the gas tank, new fuel filter, rebuilt the carb, checked the regulator pressure and am still having the issue. It does run better though. I don't have any exhaust leaks either. it is a 65 Fastback, exhaust tips through the valance, Holley 650 DP, Holley electric fuel pump w/o return fuel line. my spark plugs are not fouled or burnt after 6 years of use, they are still in pretty good shape considering the richness of the car. All seals are good and car is fairly tight. I have been converting it to a Shelby Clone so I have taken out the rear louvers and put in windows. Not sure if this has anything to do with it. I am sure it has something to do with how rich it is. I have not yet checked for vacuum leaks. maybe I will have some time this weekend.
Not to say that I am glad I'm not the only one to have this issue, because I know it sucks. I just hope we find a solution. I am not opposed to pulling the motor and going through it if that is what might be causing the issue, I am at a loss as to where to look for this.
Anything advice or links to anything would be much appreciated.

How did you do with CO? That would be a better indicator of too much fuel. High HC's indicates an ignition issue.

Wow! That's unreal. Your numbers look pretty good at 2500. Your CO also looks pretty good and doesn't change. (that's basically raw gas) HC, however is "partially burnt" gas. I would have to look at some kind of misfire at idle, maybe timing? Maybe "lean misfire"....(vacuum leak at idle?) just some thoughts, but I think what you have is the right amount of fuel, but it isn't completly burning at idle for some reason. Air mix not right? Could be a lot of things that is hard to see thru computer...how much have you done with ignition system?
