Troubleshooting & FAQ

Q: How do I confirm this carburetor fits my Yamaha or Parsun engine?

Q: What are the main differences between this aftermarket carburetor and the OEM version?
A: This replacement is manufactured to OEM specifications using comparable-grade materials in an ISO9002-certified facility. Performance and fitment match the original; the primary difference is the more competitive price point.
