What’s included and what should I expect during installation?

The shipment includes the replacement carburetor plus a gasket and O-ring to seal mounting and fuel passages. Because this product was updated over time, inspect the parts on arrival and contact the seller if you receive an older-version kit.

• One Carbhub 799868 carburetor body sized for no-choke 4–7 hp engines
• One mounting gasket and one O-ring for immediate installation
• Basic hardware typically required for swap (verify against your original parts)
• Customer support recommended if parts appear mismatched or are the older revision

Will I need extra parts or adjustments after swapping the carburetor?

In many cases the included gasket and O-ring are sufficient for a direct replacement, but some engines may require small linkages, hoses, or a fresh fuel filter. A short tune (idle and mixture adjustments) is commonly needed after install to match local fuel and altitude.

• Expect to check and replace fuel lines or filters if brittle or clogged
• Minor idle and mixture adjustments likely after installation
• Verify throttle and governor linkages align with the new carburetor
• Keep original mounting bolts and any specific brackets from your old unit
