now when I started to go on my test run, my truck was idling at 13.5 AFR by the time I came back from the test drive it richened back down to 12.5 (???)

I recall reading somewhere that the Idle Mixture screws should be somewhere between 1/2 a turn and no more than 4 turns out, so I was approaching that lower limit of 1/2 a turn to lean it out, but before messing with the Idle Air Bleeds (which I am not even sure I can replace on my carb to be honest with you) I decided to remove the carb and use my EyeCrometer to inspect the transfer slots (something you can't see with the carb on the truck)
