Damn man, does your throttle blades have holes in them? We welded mine up and was able to get the idle where needed and room for adjustment. I'm sure you'll get it man. Be patient and you'll get it.. I also had to mess with the IFRs. I know you like to figure that out yourself but you know who you could talk to if you feel you hit the end of the road with the carb.

Good luck man.
