Ferilter Carburetor for Ryobi 25cc 2-Cycle Full-Crank (307160001) — Drop-In Replacement with Installation Kit

The Ferilter 307160001 carburetor is a drop-in replacement for Ryobi 25cc two-cycle full-crank weed eaters, supplying restored fuel flow and reliable starting performance.

If your Ryobi RY25-series trimmer or compatible MTD/Craftsman equipment is sputtering, hard to start, or running inconsistently, a worn or clogged carburetor is often the cause. This Ferilter aftermarket carburetor is designed to match the fit and function of OEM parts (including MTD 753-06258A and Ryobi 307160001/307160011 variants) and ships with a full set of installation consumables so you can replace it yourself quickly.

Will this carburetor fit my specific Ryobi model?

Ferilter engineered this unit to fit many Ryobi 25cc full-crank two-cycle engines. It is compatible with common model numbers in the RY25 series and also cross-references several MTD/Craftsman part numbers.

• Designed for Ryobi RY251PH, RY252CS, RY253SS, RY254BC and related RY25 models.
• Cross-compatible with MTD/CRAFTSMAN parts such as 753-06258A and some 316-series carburetors.
• Check your engine part number against the listing before purchase to confirm fit.

How does the included hardware make installation easier?

This carburetor package includes all the small parts typically replaced during a carburetor swap, so you won’t need extra trips for gaskets or fuel lines. The spare primer bulbs and fuel filters lower the chance of leaks and air intrusion after installation.

• Package contents: carburetor, 2 primer bulbs, 2 gaskets, 2 fuel filters.
• Includes 2 fuel lines, 2 fuel line joints and an AC04122 fuel line kit for clean connections.
• Comes ready to install—helps reduce downtime and post-install troubleshooting.

What performance improvements can I expect after replacement?

Replacing a failing carburetor will typically restore consistent idle, smoother throttle response, and easier starting when the rest of the engine is in good condition. While this part addresses fuel delivery, final performance depends on overall engine health and correct adjustment.

• More reliable starts and reduced engine stalling at low throttle.
• Smoother acceleration and steadier high-speed operation when tuned properly.
• Helps prevent fuel leaks and vapor lock when installed with the new seals and lines.

How do I maintain the carburetor for long life?

Routine care prevents build-up and keeps fuel flowing properly. Use fresh mixed fuel (for two-cycle engines), store the machine with stabilized fuel or drained lines, and replace tiny filters and primer bulbs if they show wear.

• Use clean, correctly mixed gasoline and oil for two-cycle engines.
• Inspect primer bulbs, filters and hoses annually and replace as needed.
• Consider a quick carburetor cleaning if performance begins to fall off again.

Who is this for: This Ferilter carburetor is intended for DIY mechanics and small-engine owners who need a cost-effective replacement for Ryobi 25cc two-cycle full-crank trimmers, or for those maintaining compatible MTD/Craftsman/Cub Cadet outdoor tools. It’s especially useful if you want a complete hardware kit included—primer bulbs, gaskets, filters, and fuel lines—so you can finish the repair in one session without sourcing extra parts.
