Okay, so at low rpm test at 20* the stuttering still occurs. I couldn't take it higher than 20* as I lose function of my idle set screw and my driver side idle mixture screw doesnt function iether. I have backed the motor down to 16* for now, as a safety thing so as to not hurt the motor. Not sure if it will but I tend to error on the side of caution. I'm going to pull the carb once it cools down enough for me to handle it, and take a look at how my primary blades are sitting. Just making sure the transfer slots are what they are supposed to be. I'll take pictures as soon as I get it off the motor.
