Guys..in all honesty, the e2se carb is garbage! It is one of the most difficult carbs to get right. Especially the choke system.
First make sure that your engine has no vacum leaks!
Check the idle load compinsator.
An old trick was to bump the timing up about 2 degrees and then enrichen the idle mixture screw. Adjust the idle screw to raise base idle about 50 to 100 RPM.
Or just go with fuel injection
