MustangRanch

Carefully removed, fully intact.  Tucked away in a plastic sleeve with the rest of the paperwork for the car.  Thanks for the advice. 
Fyi to anybody else trying to read a tarred up sheet.  A strong light from behind shines through the tar, but not the printing.  Great way to read the hidden text.

Never knew the "Theft Protection for your Mustang" thread would apply to you eh?
What they did is wrong and violates copyright law.  As somebody who works in the web marketing industry - no, you're not due tons of money in damages, and pursuing it would probably not be worth it financially.  You could make a claim, but your legal costs / stress / annoyance / etc. would far out weigh any benefit.  It might be worth it to pursue some "in store credit" from them or something.  At best, make sure they know you know and they need to do something about it.   If you keep it light-hearted, they may respond in kind. 

Check basic stuff like vacuum leaks, etc.  If all is okay rebuild the carb again.  With todays fuel rebuilding a carb every three years is not uncommon.  This is especially true for cars that sit for long periods of time.  As the fuel in the carb evaporates it tends to leave film build up.  Eventually small passages like the idle fuel restrictors plug.  Could have also picked up small debree that plugged an idle fuel restrictor.
Have you tried covering the carb with your hand when it is idling like that?  If so, and the idle quality improves it is definitely too lean from either a vacuum leak or plugged idle fuel restrictor or idle passage.
You can try removing the idle mixture screws and spraying carb cleaner through the passage.  Also, if you know where the air bleeds are spray carb cleaner through those as well.  If it is a Holley carb, the air bleeds at the top looking straight down, 2 in each bore, very small with brass inserts.

Unless it's a skill you want to learn cause you're gonna be doing it often in the future.  And unless you feel like buying the tools cause you're gonna be doing it often in the future, my vote (and what I did when I rebuilt my brakes) is to buy them.  It is a very "doable" task and the tools and lines are not particularly expensive.  Just worked out that it was easier to buy for me.

sometimes I take cracks at these.... I'm not very good, but it's a start.

I purchased this on ebay about a year ago anticipating using it in my rebuild.  Plans change so I'm offering this up here before I return it to ebay...
 
Let me know if you're interested, I really don't know the market for these, it seems to be all over the place.  Make an offer.
