Carburetor Replaces for Briggs and Stratton 498170 122T02-1733-B1 122T02-1734-B1 122T02-1752-B1

What It Is

This is an aftermarket carburetor designed to replace specific Briggs & Stratton models (498170, 122T02-1733-B1, 122T02-1734-B1, 122T02-1752-B1). It delivers the fuel-air mixture to the engine and is commonly used on walk-behind lawn mowers, riding mowers, and pressure washers with these engines.

Fitment & Compatibility

Before buying, verify three things:

1. Engine model number – Look for a 12-digit number on the engine shroud or near the spark plug. This carb fits models 122T02-1733-B1, 122T02-1734-B1, and 122T02-1752-B1. It also directly replaces OEM part 498170.
2. Deck size doesn’t matter – Fitment is engine-specific, not mower brand or deck width. Works with Craftsman, Troy-Bilt, MTD, Husqvarna, and other mowers using those engines.
3. OEM vs. aftermarket – This is a non-OEM part. It may require minor adjustments (e.g., idle speed screw) and may not have the same long-term durability as an OEM Briggs carburetor. Measure the mounting bolt spacing (typically 60mm center-to-center) to confirm.

Key Things to Know

• Installation difficulty: moderate – You’ll need a socket set, screwdriver, and possibly a carburetor gasket. Expect 30–60 minutes. Watch for small springs and linkage clips that are easy to drop.
• Adjust the idle screw – Aftermarket carbs often come with the idle speed screw set too high or low. Start the engine and adjust until the engine idles smoothly without stalling.
• Check the gasket – The included gasket is thin. If your old gasket is still pliable, reuse it. If not, consider buying a separate gasket kit to prevent air leaks.
• Fuel line fit – The barbed fuel inlet is standard 1/4-inch. If your fuel line is brittle or cracked, replace it while you’re at it.

Should You Buy It

This is a solid budget option if you’re comfortable with basic engine work and want to get a mower running quickly. It’s not for professional landscapers or those expecting OEM-level longevity. If you need a quick fix for a seasonal mower or second machine, it’s a good value at this price.
