All well said, except "close choke" is confusing. It really should be "fully turn off enricher". If you want to use the choke analogy, then it would be "open choke".
defaultstivaper, the enricher system lifts a poppet valve type of plunger off a hole. When this happens, fuel
and air are added to the mixture. Partially opening it is likely to allow more fuel than air into the mix. That's probably why you found that raising the idle speed helped. If you fully open the enricher, that should take care of the need to raise the idle speed automatically.
Correct adjustment of the enricher cable is needed. It should seat and not leak when off, but without so much slack that it doesn't fully open. I'm sure the manual tells how to adjust it, but if you look carefully you should be able to adjust it so that there is only a small amount of cable slack when it's fully off.
