Jet size on the E-Z-GO Shuttle 2+2 RXV applies only to the older carbureted version; later EX1 EFI versions have no carburetor jets. Match the engine and carburetor ID before ordering.
Shuttle 2+2 RXV • Main & pilot jet sizes
Shuttle 2+2 RXV carburetor jet sizes at a glance
Main jet
Pre-EFI only: match the main jet to the exact engine and carburetor ID.
Pilot jet
Pre-EFI only: match the pilot jet to the exact engine and carburetor ID.
Altitude
Use the manufacturer altitude chart where one is published.
Before ordering
Identify the engine and carburetor, then read the number stamped on the existing brass jet.
Lean symptoms
Needing choke, surging or load bog can also come from a clogged passage, weak fuel supply or intake leak.
Rich symptoms
Black smoke or plug fouling can also come from a stuck choke, high float level or leaking needle valve.
How to choose the correct E-Z-GO Shuttle 2+2 RXV jet
Shuttle 2+2 RXV jetting symptoms
Needs choke to run
Clean the pilot and main circuits and check fuel supply and an intake leak before fitting a larger jet.
Bogs under load
A restricted main jet can cause this, but so can weak pump flow, low bowl fuel level or a blocked filter.
Black smoke / fouled plug
Check choke position, float level and needle sealing before assuming the main jet is too large.
Runs well only at low speed
Main-jet or main-nozzle restriction becomes more likely once the pilot circuit is known to be clear.
Poor idle only
The pilot circuit matters much more than the main jet at idle.
High-altitude operation
Use the model-specific elevation chart where available; do not guess how many jet sizes to reduce.

E-Z-GO Shuttle 2+2 RXV carburetor jet FAQ
What is the E-Z-GO Shuttle 2+2 RXV main jet size?
Pre-EFI only: match the main jet to the exact engine and carburetor ID. Later EX1 EFI Shuttle 2+2 RXV versions do not use carburetor jets. Confirm the older carbureted engine before ordering.
What is the E-Z-GO Shuttle 2+2 RXV pilot jet size?
Pre-EFI only: match the pilot jet to the exact engine and carburetor ID.
Does altitude change the E-Z-GO Shuttle 2+2 RXV main jet?
Use the manufacturer altitude chart where one is published.
Can I install a larger jet in an E-Z-GO Shuttle 2+2 RXV?
Only after confirming the engine, carburetor, altitude and cause of the lean symptom. A clogged passage, intake leak or weak fuel supply should not be corrected with an oversized jet.
How do I identify the correct E-Z-GO Shuttle 2+2 RXV carburetor jet?
Use the stamped jet number together with the engine code, carburetor ID and model year. Cross-check those identifiers against the matching factory parts or service information.
What is the difference between the main and pilot jet on an E-Z-GO Shuttle 2+2 RXV?
The pilot circuit controls idle and very low-throttle fueling. The main jet becomes dominant as airflow, throttle opening and engine load increase.
Jet sizes can change with engine, carburetor revision, model year and altitude. This page applies to the older carbureted gasoline version. Do not drill jets or assume a jet from another model is equivalent. Confirm the engine, carburetor ID and existing jet markings for your exact E-Z-GO Shuttle 2+2 RXV.
