the problem with the edelbrock is that it is toooooo adjustable, I used one once, first it was causing a lean misfire on the top end (at WOT under load the engine would start popping back through the carb around 4200 rpms), went through dozens of springs and jets, eventually I got it right. the symptoms associated with lean firing conditions (whether at WOT or at part throttle) can be easily mistaken for ignition problems.
