Carburetor jets are the small, metering orifices that control fuel flow through your carburetor's circuits. A correctly sized jet delivers the precise air-fuel ratio your engine needs—whether you're dialing in a stock restoration or tuning for altitude, temperature, or performance modifications. Swapping jets is one of the most direct ways to eliminate bogging, flat spots, or an overly rich idle.

This collection covers a range of common jet styles, thread pitches, and flow ratings so you can find the right match for your carburetor body. Look for details like orifice diameter (often measured in thousandths of an inch or millimeters), material (typically brass or stainless for corrosion resistance), and compatibility with specific carburetor families.

• Precisely drilled orifices ensure consistent metering
• Common materials: brass, stainless steel
• Available in a wide span of flow sizes to fine-tune the fuel curve
• Suitable for main jets, pilot/slow jets, and air bleed circuits (verify style before ordering)

If you're unsure which size or style you need, consult your carburetor's factory service manual, or use a jetting calculator based on current air density and engine state of tune. Always change jets in small increments and read spark plugs to confirm the mixture is safe and efficient.
