01 / HIGH-ALTITUDE OPERATION
WHY HIGH ALTITUDE CHANGES THE FUEL MIXTURE.
As elevation increases, atmospheric pressure and air density decrease. Each intake cycle carries less oxygen mass than at lower elevations. A carburetor calibrated for denser air can produce an overly rich mixture when operated in thinner air.
01
LOWER AIR DENSITY
Higher elevations mean less dense air enters the engine during operation, reducing the available oxygen for combustion.
02
RICH FUEL MIXTURE
A standard carburetor calibration may supply more fuel relative to the available air, potentially affecting starting, combustion, fuel consumption and performance.
03
ALTITUDE-SPECIFIC JETTING
The correct high-altitude main jet changes fuel metering to better match the intended operating elevation.
Important:
A high-altitude jet adjusts the carburetor
fuel mixture. It cannot restore oxygen
lost through reduced air density or
guarantee full sea-level rated power.
Engine performance may still decline
above 8,000 ft.
02 / MAIN JET TECHNICAL SPECIFICATIONS
TWO JET MARKINGS. TWO ELEVATION BANDS.
Both replacement jets share the same illustrated overall form, while the stamped identification number differs. Match the actual jet marking and package label to the elevation where the ERAYAK 2400P will operate.

INSTALLATION OVERVIEW
3 Main Stages
01
REMOVE THE FLOAT BOWL
After shutting down and cooling the engine, isolate the fuel supply and remove the float bowl according to the service instructions.
ACCESS THE INTERNAL MAIN JET
02
REPLACE THE MAIN JET
Remove the original main jet and install the correct altitude-specific replacement based on the operating elevation.

03
REPLACE SEALS & REASSEMBLE
Install the new bowl gasket and bottom washer/seal. Carefully reassemble the float bowl and fastening components according to the official instructions.
CHECK GASKET SEATING AND SEALING
Service requirement:
Carburetor disassembly and
fuel-system maintenance should
be performed by a qualified
individual. Follow the official
operation instructions and
never cross-thread or
overtighten the bowl bolt.
05 / OPERATING RANGE & LIMITATIONS
MATCH YOUR JET TO YOUR ELEVATION.
Selecting the correct main jet depends on the elevation where the engine will operate. The supplied jets cover two clearly labeled altitude bands.
STANDARD CONFIGURATION
0–3000 ft
The general operation instructions state that a high-altitude jet is not required from 0–3000 ft.
MAIN JET #67
1000–2000m
Approximately 3,281–6,562 ft. Use the jet marked #67 for the specified operating altitude.
MAIN JET #65
2000–3000m
Approximately 6,562–9,843 ft. Use the jet marked #65 for the specified operating altitude.
Operating limitations:
The two supplied jets are labeled
for elevations up to 3000m
(approximately 9,843 ft).
Do not assume compatibility
beyond the specified range.
Above 8,000 ft, engine
performance may still decrease
even when the correct
high-altitude jet is installed.
Returning to lower elevation:
If the generator is moved to
a location below 3000 ft,
the original main jet should
be reinstalled according to
the operation instructions.
Keep the original jet for
future use.
06 / SERVICE & SAFETY
INSTALL SAFELY. OPERATE RESPONSIBLY.
High-altitude jet replacement involves carburetor disassembly and gasoline fuel-system service. Follow the supplied operation instructions and all generator safety requirements.
01
ENGINE OFF AND COOL
Shut down the engine and allow it to cool thoroughly before opening or servicing the carburetor.
02
PREVENT FUEL FLOW
Clamp the fuel hose or drain gasoline as instructed before disconnecting the carburetor.
03
AVOID IGNITION SOURCES
Work in a well-ventilated area away from flames, sparks, hot surfaces and other ignition sources.
04
CHECK FOR LEAKS
Install the new seals correctly. Clean spilled gasoline and allow remaining vapors to dissipate before restarting.
Generator operation reminder:
Always operate the generator
outdoors and far from doors,
windows, vents, tents, RV
openings and occupied areas.
Never operate a gasoline
generator inside a home,
garage, tent or RV.
Use a qualified individual
for carburetor service.
07 / TECHNICAL FAQ
FREQUENTLY ASKED QUESTIONS.
Key information about altitude selection, carburetor adjustment, compatibility and operation.
Why are two different main jets included?
The two jets are intended for different operating elevations. Jet #67 is labeled for 1000–2000m, while jet #65 is labeled for 2000–3000m. Only the correctly selected main jet is installed at one time.
Which jet should I use at 9,000 ft?
9,000 ft is approximately 2,743m, which falls within the labeled 2000–3000m altitude range for jet #65. Always verify the actual generator model and supplied instructions before installation.
Will the kit restore full power at high altitude?
No full-power restoration is guaranteed. The high-altitude jet helps adjust carburetor fuel metering for thinner air. The operation instructions note that engine performance may still decrease above 8,000 ft.
Can I use the high-altitude jet at sea level?
The high-altitude jets are designed for their specified elevation ranges. The supplied instructions advise reinstalling the original main jet when the engine is moved below 3000 ft.
Is the kit compatible with other ERAYAK generators?
This kit is listed for the ERAYAK 2400P inverter generator. Other generator models may use different carburetor configurations and main-jet specifications. Confirm compatibility with ERAYAK before ordering.
Can I install the kit myself?
Installation involves gasoline handling and carburetor disassembly. The supplied operation instructions recommend installation by a qualified individual.
What is included in the kit?
The kit includes one #67 high-altitude main jet, one #65 high-altitude main jet, one bowl gasket, one washer/seal and the operation instruction sheet.
