Troubleshooting & FAQ
How do I know if my carburetor gasket is failing?
Common signs include a rough idle, engine stalling, poor acceleration, or a noticeable vacuum leak hiss near the carburetor base. Fuel stains around the gasket area also indicate a failure.
Can I reuse my old gasket?
No. Carburetor gaskets are single-use components designed to crush and seal. Reusing an old gasket will likely result in air or fuel leaks.
Is there a specific orientation for this gasket?
Yes, always match the new gasket's shape to the bolt pattern and intake port on the manifold. It should only fit correctly in one orientation.
How often should this part be replaced?
Replace the gasket whenever the carburetor is removed for service, cleaning, or rebuilding. It does not have a set replacement interval but should be inspected for brittleness or damage during routine maintenance.
My engine model is listed, but the year is slightly different. Will it fit?
Fitment can be very specific. If your exact model and year combination is not listed, we recommend verifying the part number with your engine's service manual or contacting us with your engine's full model and serial number before ordering.
