Carburetor Carb Assembly Compatible with Briggs & Stratton Part# 84002023 84002107,WITH AIR FILTER 593260

What It Is

This is an aftermarket carburetor assembly (with air filter) designed to replace Briggs & Stratton part numbers 84002023 and 84002107 on single-cylinder engines found on walk-behind mowers, lawn tractors, and small utility engines.

Fitment & Compatibility

Before buying, verify your engine model number (stamped on the blower housing or valve cover) and confirm it lists B&S part# 84002023 or 84002107 as the OEM carb. This kit includes the carburetor and a pre-filter (part# 593260), but does NOT include a fuel line, gaskets, or mounting bolts. Measure your carb mounting flange bolt spacing (typically 2.125" or 2.375" center-to-center) to match. It fits most 5–10 HP engines, including Series 450, 500, 550, 575, 600, and 625 engines, but not all—check your specific model.

Key Things to Know

• Quality varies: Aftermarket carburetor—expect potential fitment gaps, plastic vs. metal parts, and possible need for adjustment. Not OEM-grade.
• Installation difficulty: Moderate. You’ll need to remove the old carb, clean the intake port, transfer your old gaskets (or buy new ones), and adjust the idle mixture screw (if adjustable). Expect 30–60 minutes.
• Common gotchas: The included air filter may be a universal foam type—check if it fits your air box. Also, the carb may need a fuel line adapter if your hose diameter is ¼” vs. 5/16”.
• No return on installed parts: Since it’s a cheap aftermarket unit, test fit before final assembly. Many sellers won’t accept returns once fuel has been run through it.

Should You Buy It

This is a budget-friendly fix for a non-critical mower or a secondary machine where you’re comfortable with minor adjustments and potential fit tweaks. If you need a drop-in, long-lasting replacement for a primary mower, spend more on a genuine B&S carb or a premium aftermarket brand.
