What It Is

This carburetor kit with nozzle replaces the fuel delivery system on Troy-Bilt pressure washers powered by Briggs & Stratton 7.75 HP, 8.75 HP, 8.5 HP, or 190cc engines. It also fits compatible 2700 and 3100 PSI units, serving as a drop-in fix for engines that won’t start, surge, or run rich.

Fitment & Compatibility

Before buying, verify three things:

• Engine make & model: Confirms fit for Briggs & Stratton engines listed (7.75/8.75/8.5 HP or 190cc). Will not fit Honda, Kohler, or other brands without adapter kits.
• Pressure washer PSI: Works with 2700 and 3100 PSI Troy-Bilt units. Not for lower or higher PSI models unless engine matches.
• OEM part numbers: Replaces Briggs #796608, 591137, 590948, 594287, and 799248. Cross-check your engine’s part number on the carburetor or service manual.
• Physical dimensions: No universal measurement—compare gasket and mounting holes with your old carb. Nozzle type (e.g., threaded vs. press-fit) must match your existing fuel line.

Key Things to Know

• Quality vs. OEM: Aftermarket at $20.99 vs. $40–60 OEM. Works fine for most repairs, but may need minor adjustment (idle screw) out of box.
• Installation difficulty: Moderate. Requires removing air filter, fuel line, and two bolts. Expect 20–40 minutes. No special tools beyond a socket set and needle-nose pliers.
• Common gotcha: The nozzle can be loose if not fully seated—tighten gently to avoid stripping. Also, old gaskets may leave residue; clean mounting surface thoroughly to prevent vacuum leaks.
• Fuel system prep: If the old carb failed due to stale gas or debris, also replace the fuel filter and drain the tank to avoid repeat issues.

Should You Buy It

This kit is a solid, budget-friendly fix for DIYers who can handle basic engine work and have a compatible Troy-Bilt pressure washer with a Briggs engine. It’s not for pros needing guaranteed long-term durability or those with non-Briggs engines. If you want a simple swap without adjusting idle screws, stick with OEM.
