Need help with emissions...

Has anybody caught this Intense Dakota writes; I am going to tear down the carb this weekend and find out what jets are in it becuase the car came from Colorado and I am in Illinois. Sense most sea level 1850`s came with 72/76 jets, its probably lean, it was more than likely jetted down for the mile high city....? what do you guys think...? Also may even have the wrong power valve?
