What is the correct method to clean clogged brass jets (pilot jet and main jet) during a carburetor overhaul?

1. Soak in carburetor cleaner solvent and blow out with compressed air; never use steel wire or drills to clean the orifices.
2. Ream the jet holes with a steel sewing needle or thin guitar string to scrape off deposits.
3. Burn the jets with a propane torch until they glow red, then drop them in cold water.
4. Scrub the inside of the jet orifices with a stiff wire brush and coarse sandpaper.
