Welp, after screwing with this carb for months dealing with this condition, I've just decided to cut my losses. Switch back to gas and put
my trusty Holley 9380 850 double Pumper back on. I tested it today.No more stumble while rolling to a stop !! HALLELUJAH!! .. Perhaps relocating the IFR's down low would have fixed it?.. but still , I didnt wanna go drilling away on the carb based on what is still just a guess in my opinion.
Wanted to say thanks to anyone who gave feed back or offered input. I'm gonna sell the carb, hopefully the guy who buys it can tune an E85 carb better than me.
