First off I know very little about carbs other than their basic functions. I started this because I wanted to lower the idle because sometimes (about half the time) the transmission hits hard in reverse and drive . I just got this truck so upon inspection I can tell the carb is probably not in the best condition. I believe the 4 barrel may not even be hooked up. I thought I may post some pics and someone might tell me what stands out to them and make suggestions. Thanks!
