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 Club Car XRT 900 jet

Confirm that this Club Car XRT 900 matches the fe350 carbureted gasoline version described here.

Engine/application: Kawasaki FE350 gasoline. Carburetor: FE350 fixed-jet float-bowl carburetor.

Remove the bowl and jets only after cleaning the carburetor exterior. Read the stamped jet number; do not estimate jet size from hole diameter or appearance.

Main jet: #85 at 0–3000 ft; #82 at 3000–5000; #80 at 5000–8000; #78 at 8000–10,000; #75 at 10,000+. Altitude guidance: Factory FE350 elevation chart: #85 / #82 / #80 / #78 / #75 as altitude increases.

Pilot jet: Use the fixed pilot jet for the exact carburetor revision. If it only runs with choke or will not idle, clean the pilot circuit and check for an intake leak before changing the jet size.

After fitting the correct jets, verify warm idle, clean takeoff and full-load response. If the problem remains, check fuel level, float, needle valve, choke and fuel-pump delivery before changing jet size again.

XRT 900 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.

The pilot circuit controls idle and very low-throttle fueling. The main jet becomes dominant as airflow, throttle opening and engine load increase.

Verify the jet before ordering

Jet sizes can change with engine, carburetor revision, model year and altitude. This page applies to the fe350 carbureted gasoline version.
