Troubleshooting & FAQ

How do I confirm this carburetor fits my Yamaha engine?

It directly replaces Yamaha part numbers 66M-14301-11-00, 66M-14301-12-00, and others listed in the cross-reference table.

Will this fit my Parsun or Hidea motor?

What are the signs that my old carburetor needs replacing?

Common symptoms of a failing carburetor include difficulty starting, rough idling, engine stalling at low speeds, poor acceleration, fuel leaks, or black smoke from the exhaust. These issues often indicate that a cleaning is insufficient and a replacement is required.
