Troubleshooting & FAQ
How do I know if this carburetor is for the #1, #2, or #3 position?
This carburetor assembly is specifically designed and calibrated for the #1 cylinder position in a 3-carburetor configuration. It is not interchangeable with the #2 or #3 carburetors.
Will this fit my Yamaha 90HP engine?
This part fits specific Yamaha 90HP, 3-cylinder, 2-stroke models made from 1999–2006. It is essential to verify your engine's exact model ID and year by checking the engine plate and comparing it against the compatibility table provided on this page.
Do I need to adjust the carburetor after installation?
The carburetor is preset to factory baseline specifications. However, due to variations in engine wear, altitude, and fuel, minor adjustments to the idle mixture and/or idle speed may be necessary for optimal performance. Always refer to your engine's service manual for the correct procedure.
What are the common signs my carburetor is failing?
Symptoms of a bad carburetor include difficulty starting, rough or erratic idling, engine stalling at low speeds, hesitation or poor acceleration, black smoke from the exhaust (running rich), and visible fuel leaks around the unit.
What is the difference between all the OEM part numbers listed?
The various part numbers (e.g., 6H1-14301-07-00, 6H1-14301-30-00) represent OEM revisions made by Yamaha over the years. This aftermarket part is engineered to replace all listed superseded and current numbers, providing the same fit, form, and function.
