Hey guys. I have a 57 tbird with a 312. It has a new Holley 4160 465 cfm carb on it. I seem to get significantly more carbon coming out of the left side than the right. I have the mixture screws turned out 1 1 / 2 turns out equally on both sides. Should the screws be turned out the same amount?



What is optimal temperature for these engines to run at? My car generally runs at about 175 - 180 degrees (right in the middle of the temp gauge). I find that when I get into stop and go traffic and the temp starts to creep up the car seems to run cleaner - the acceleration from a stop seems crisper and not as boggy.



Thanks
