Lean idle. Rich cruise.
Phew! That's a lot to digest. But first step is to plug those emulsion bleeds mentioned and make sure idle feeds are in the lower position. Have to order some .026 Main air bleeds. So those 3 things I will try in one step. Usually don't like trying more than 1 change at a time. But it makes sense.
As far a carbs go, Id love to find a 2008 ish HP 950. Don't know why they quit making them but I've had really good results with several. Shoulda never sold the last one I had.
Drill a couple holes in the throttle plate and you're pretty much just jetting. Easy peasy. They just make **** more difficult every new "better" generation.
