795477 Carburetor Compatible for Briggs and Stratton 3.5 hp Carburetor Poulan 550 Series Engines, Fits 795475 795469 with 698369 Air Filter Spark Plug

What It Is

This is an aftermarket carburetor assembly designed to replace the fuel system on small engines, specifically for Briggs & Stratton 3.5 hp engines and Poulan 550 series trimmers, blowers, or edgers. It includes the carburetor, air filter (698369), and spark plug, making it a complete tune-up kit for basic maintenance.

Fitment & Compatibility

Before buying, verify your engine’s model number (e.g., 3.5 hp Briggs & Stratton or Poulan 550 series). The carburetor replaces OEM part numbers 795477, 795475, and 795469. It fits most 2-cycle engines in these series, but not 4-cycle engines. Measure the mounting hole spacing (typically 1.5” center-to-center) and check if your machine uses a primer bulb or choke—this carb has a primer bulb. The included spark plug is a standard J19LM or equivalent; confirm your engine’s plug gap (usually 0.030”). This is an aftermarket part, not OEM, so expect slight differences in plastic quality or gasket fit.

Key Things to Know

• Quality: Budget-friendly, but some users report needing to adjust the idle mixture screw (if adjustable) for smooth operation. Non-adjustable models may require cleaning out debris from shipping.
• Installation difficulty: Moderate—requires removing old carb, swapping gaskets, and reconnecting fuel lines. The included air filter may not fit tightly; double-check the housing.
• Common gotcha: The spark plug may be pre-gapped incorrectly; always check and set gap before installing. The carburetor can leak if gaskets are misaligned—use a thin layer of fuel-resistant sealant on mating surfaces.
• Performance: Works well for light-duty use (trimming, edging), but may not hold up under heavy continuous load (e.g., commercial mowing). Expect to clean the carb after a season of use.

Should You Buy It

Buy this if you need a quick, low-cost fix for a small engine that won’t start or runs rough, and you’re comfortable with basic mechanical work. It’s ideal for DIY homeowners with Poulan or Briggs 3.5 hp equipment who want a complete tune-up kit in one purchase. Avoid if you need OEM reliability for professional use or have a 4-cycle engine.
