Tutti Ricambi #160 Air Jet - Dellorto SI Carburetors

This Tutti Ricambi #160 air jet helps you fine-tune the air entering the main jet stack of a compatible Dellorto or Spaco SI carburetor. Positioned above the atomizer, this air-correction jet admits air that mixes with fuel before it reaches the engine. Its threaded end and slotted head make it a practical replacement or tuning component for your vintage Vespa or Stella's matching SI setup.

Key Features

• #160 calibration: Provides the 160-size air-correction option for a compatible SI jet stack.
• Top-of-stack position: Installs above the atomizer rather than replacing the fuel main jet.
• Slotted head: Accepts a flat-blade screwdriver for installation and removal.
• Threaded fitting: Screws into the matching SI carburetor jet-stack location.
• Tuning flexibility: Lets you adjust air correction as part of a coordinated main-jet and atomizer setup.

Compatibility

Confirm the carburetor type and existing jet-stack configuration before ordering, especially on scooters with carburetor conversions. Model name alone does not determine the correct jet calibration.

Within this air-jet family, a larger size number allows more air through; it does not indicate greater fuel flow. Choose the air jet together with the main jet and atomizer, then check and adjust the complete setup for your engine. The air-jet range also includes 120 and 185 sizes, sold separately. See our carburetor jetting guide for more information.
