Also, adjustment of pilot air or pilot fuel screw. See range, speed, seating, and a quick chart, plus how to choose, costs, and FAQs. 5 turn for a proper idle/warm up time How do you tell if your pilot jet is too lean, rich, or just right?

Keep your 182 main jet and consider dropping your pilot back down to a 42. The pilot (air/fuel) screw only adjusts fuel flow to one of these orifices. Other indications that the pilot circuit is lean are popping or spitting through the carburetor when the throttle Would this be a good indication that the pilot is too lean?
