Try turning the idle jets 1/2 turn richer. (Counter clockwise).

This was my thought as well, sounds like it is running too lean.

Before you go richer, go leaner.
Turn one screw in slowly until the idle changes. If you can turn it all the way in with no change then you’re idling on the power circuit and the transfer slot is fully exposed.
No amount of mix screw fiddling will help.

This!

This is what happens when you don't square the transition slots.
