If meticuously cleaning the orifice plug isn’t getting it done….then suggest that he remove the welch plug which exposes the idle system jets…..and meticuously clean that area.
I recently had a 9.5 that was doing exactly that….needed choke to run at idle and was lean-missing all over the place. Was shaking sooooo bad lol….
I could spray carb cleaner through the needle valve opening and I could see it squirting through the three idle holes in the carb throat. I even poked wires through the three holes in the throat….all three holes seemed open and clear from the throat side.
Still ran poorly so I popped the welch plug….cleaned everything from that side….and the problem was fixed. 9.5’s seem to be particularly sensitive to a **very** clean carb.
