The MIKUNI 003.339 176-P6 Needle Jet is a precision carburetor component designed for use in compatible Mikuni carburetor assemblies. As part of the carburetor metering system, the needle jet works with the jet needle to help regulate fuel flow through the main circuit during engine operation. Its precise internal passage supports consistent fuel delivery and dependable throttle response when properly matched to the carburetor, engine, and other tuning components.
The 176-P6 designation identifies the needle jet specification, while MIKUNI part number 003.339 provides a direct reference for ordering and replacement. This component is intended for maintenance, rebuilding, or tuning applications where the existing needle jet is worn, damaged, contaminated, or no longer appropriate for the desired fuel calibration. Replacing a needle jet with the correct specification can help restore proper carburetor performance and maintain predictable operation across the engine’s operating range.
Before installation, confirm compatibility using the carburetor model, needle specification, engine application, and manufacturer service information. Needle jets are precision-fit components, and selecting the correct series and profile is important for achieving the intended fuel mixture. Inspect the carburetor body, jet needle, retaining components, and surrounding passages during service, and clean the assembly carefully to prevent debris from affecting fuel flow. Install the MIKUNI 176-P6 Needle Jet according to the applicable service procedure and verify carburetor adjustment after assembly.
