You'll want to remove main jet from emulsion (holder) tube so you thoroughly scrub it on inside. Chads tend to hang on inside after being poked through from outside. Also micro soda-blast inside.
Make sure needle jets/collars are installed with proper orientation. End with internal taper faces needle.
And poke out bleed-hole in carb-venturi with wire where mixture-screw goes through. Due to taper, deposits get formed into cone shape and appears to flow when pilot is removed. But will block flow when installed.
