Troubleshooting & FAQ

Q: How do I confirm this kit fits my engine?
A: Cross-reference your engine's horsepower, model year, and configuration (V4 or V6) with the compatibility table above. Verify that your original carburetor uses one of the listed OEM part numbers (390055, 392550, 398526, 434888, 435443, 439076) or Sierra 18-7046.

Q: What should I do if my engine still runs rough after installing the kit?
A: Verify that all gaskets and O-rings are properly seated and that the float height is correctly adjusted. Check fuel delivery, spark plugs, and ignition timing, as carburetor issues may be secondary to other system faults.

Q: How often should I rebuild my carburetor?
A: Rebuild intervals depend on fuel quality, storage conditions, and usage. If you experience hard starting, rough idle, or fuel leaks, it's time to rebuild. Preventive rebuilds every 3–5 years are recommended for engines in regular use.

Q: Can I use this kit on 60° Looper models?
A: No, this kit is not compatible with 60° Looper configurations. Verify your engine type before ordering; the kit fits standard V4 and V6 Crossflow designs only.

Q: What are the signs that my carburetor needs rebuilding?
A: Common symptoms include difficulty starting, unstable idle, fuel leaks around the bowl, poor acceleration, and excessive fuel consumption. Worn gaskets, seats, and O-rings are typical culprits.
