But, IMO, a 1986 with 41,000-some odd miles (66,500 to us Canadians), that was driven in regular intervals, shouldn't need that much time to "warm up." Within 10 minutes of starting it, if I put my foot down any more than...1/4 of the way, it starts to bog out. I can deal with it for now, seeing as how it WILL be coming off for a 600 CFM sooner or later...I'm just curious as to why it chokes so bad.

First of all, you need to check to make sure that your choke is going off when the engine is warmed up. that would definately cause a rich condition! and if its not working at all, the car will run pretty funny. check and make sure all of your vacuum hoses are intact, and not cracked. check the exhaust gas recirculation (EGR) valve, and the charcoal tank if applicable. they have been known to cause random vacuum leaks. if so, your vacuum advance.. (where they still using vacuum advances? i think so) wouldnt work, and the timing would be retarded substantially. is it a rochester quadrajet? i dont know what they came with. the quadrajet is a wonderful carb when tuned correctly, contrary to popular belief, they are the most advanced design for a carburetor ever made. they are infinitely tunable, and will get incredible gas mileage. send me an email rback223@hotmail.com if you have specific questions! i would love to help!
