Carbman Carburetor Kit for Vanguard 16–18HP Engines (Fits 350447/356447) with Gaskets, Direct Replacement

Carbman 846109 is a direct-replacement carburetor kit with gaskets designed to restore reliable fuel delivery for Vanguard 16–18HP engines and compatible Argo ATV models.

If your small engine is running rough, hard to start, or suffering power loss, a worn or damaged carburetor is often the cause. This Carbman assembly replaces a wide range of OEM part numbers and fits specific Briggs & Stratton Vanguard engines (350447 and 356447 series) as well as select Argo ATVs, giving you a factory-style fit and the included gaskets for a cleaner installation.

Which engines and machines will this carburetor work with?

This unit is built to match the specifications of multiple OEM part numbers and engine models used in Vanguard 16HP, 17HP and 18HP engines. It’s also listed as compatible with certain Argo ATVs and engine spec numbers for Briggs & Stratton Vanguard series.

• Replaces Carbman/OEM numbers like 846109, 809017, 808253 and many others
• Compatible with engine codes 350447 and 356447 in various suffixes
• Fits Argo models such as Bigfoot 6x6 and Frontier 580 6x6 (model years noted)
• Includes a full gasket set to ensure proper sealing on installation

How easy is installation and what comes in the kit?

The carburetor comes preassembled with a matched gasket set to simplify swapping it into your engine. Basic hand tools are usually sufficient for a competent DIYer; follow torque specs and fuel/air line routing of the original unit.

• Complete carburetor assembly ready to mount
• Gaskets included for intake and mounting surfaces
• No specialized tools required beyond standard wrenches and screwdrivers
• Installation time typically ranges from 30 minutes to 2 hours depending on access

Will this restore performance and prevent further problems?

Replacing a worn or leaking carburetor with a correct-fit replacement restores proper fuel metering and idle stability, reducing stalling and poor throttle response. While it fixes carburetion-related issues, inspection of fuel filters, fuel lines and ignition components is recommended for a complete tune-up.

• Improves throttle response and cold starts if carburetor was the cause
• Included gaskets help stop air or fuel leaks at mounting points
• Works alongside routine fuel system maintenance for best results
• Not a solution for electrical or compression-related faults

What part numbers and compatibility checks should I perform?

Before ordering, compare the part numbers stamped on your original carburetor and note your engine’s spec number. This Carbman unit lists many cross-reference numbers to help confirm fitment—matching those numbers reduces the chance of returns.

• Cross-check OEM numbers like 846109, 809017, 808370, 843324 and more
• Confirm engine spec codes such as 350447-1026-A1 or 356447-0165-E1
• Verify vehicle model fit (e.g., Argo Bigfoot 6x6 1999 and newer)
• Contact seller support if you’re uncertain; assistance is available within 24 hours
