I always remove the Welch plug and inspect the idle circuit underneath. There is no other way to inspect the orifice where the slow speed needle seats and I’ve seen them chipped and I’ve seen the tip of a needle lodged in the orifice. If you have the kit, the plug is included and it doesn’t take much effort to remove it. Just drill a small hole in the old one and pry it out.
