Overview
The iFJF Carburetor 394352 is a direct OEM-spec replacement for Briggs & Stratton Intek V-Twin engines ranging from 14 to 18 horsepower. These engines power many of the most popular riding lawn mowers, zero-turn mowers, and lawn tractors from brands including Craftsman, Husqvarna, John Deere, Poulan Pro, and Toro. When your carburetor is gummed up from old fuel, has worn internal components, or simply won't hold a tune anymore, this replacement restores easy starting, smooth idle, and responsive throttle control.
Rather than spending $80-120 on an OEM Briggs carburetor or $150+ at a small engine repair shop, this iFJF replacement delivers equivalent performance and fit at a fraction of the cost. Each carburetor is pre-adjusted and includes new mounting gaskets for a complete, hassle-free installation.

FAQ
Q: Will this carburetor fix my hard-starting mower?A: If the hard starting is caused by a gummed-up, clogged, or worn carburetor (which accounts for the majority of small engine starting issues), yes. If the problem is ignition-related (bad spark plug, coil) or compression-related, a new carburetor won't help. The most common symptom of carburetor failure is the engine only running with choke partially engaged.
Q: Does it come pre-adjusted for my engine?A: Yes. Each carburetor is factory pre-set to approximate specifications for Briggs Intek V-Twin engines. Minor idle speed and mixture adjustments may be needed based on your specific engine, altitude, and climate. Most installations require no adjustment beyond the factory settings.
Q: Will this fit my John Deere riding mower?A: If your John Deere mower uses a Briggs & Stratton Intek V-Twin engine (14-18HP), yes. Many John Deere 100 Series, D Series, and LA Series lawn tractors use these engines. Verify your engine model number before ordering — it's stamped on the valve cover.
Q: Is ethanol fuel safe for this carburetor?A: This carburetor is compatible with E10 gasoline (up to 10% ethanol). For maximum carburetor life, we recommend: using fresh fuel (less than 30 days old), adding fuel stabilizer if the mower sits for more than 2 weeks, and running the carburetor dry before winter storage. Ethanol-blended fuel left sitting in the carburetor is the #1 cause of carburetor failure.
Q: Do I need to replace the fuel filter at the same time?A: While not required, it's highly recommended. If the old carburetor was gummed up, debris may have been circulating in the fuel system. A new fuel filter ($5-10) is cheap insurance to protect your new carburetor from contamination.
Q: How do I know if I need a new carburetor vs. just cleaning the old one?A: If the old carburetor is simply gummed from old fuel and less than 3-4 years old, cleaning may restore it. If the engine has more than 200 hours, the carburetor shows visible corrosion, or internal passages are permanently clogged, replacement is more reliable and often more cost-effective than the labor of multiple cleaning attempts.
Q: Is this an OEM Briggs & Stratton part?A: This is a high-quality aftermarket replacement manufactured to Briggs & Stratton OEM specifications. It provides equivalent fit and performance at a significantly lower cost than the OEM-branded 394352 part.
Q: Will this work with my existing air filter and intake?A: Yes. The mounting flange and intake interface match the OEM Briggs specification exactly. Your existing air filter assembly, intake manifold, and fuel line will connect directly to this carburetor without modification.
