84001033 Carburetor For Briggs & Stratton 594926 596475 104M02 Engine Replaces 84001032 595895 With Air Filter Cover

What It Is

This is a complete carburetor assembly for small Briggs & Stratton engines, specifically the 104M02 series. It replaces OEM part numbers 84001032 and 595895, and includes the air filter cover. Common on walk-behind mowers, pressure washers, and generators.

Fitment & Compatibility

• Engine models: Fits Briggs & Stratton 594926, 596475, and 104M02 (check engine model number stamped on the blower housing or valve cover).
• OEM cross-reference: Replaces 84001032, 595895, and 84001033. If your machine uses part 84001033 or 84001032, this fits.
• Deck size not relevant – compatibility is engine-only, not mower deck.
• Measurement check: Compare the mounting flange bolt spacing (approx. 2.5 inches center-to-center) and the intake port diameter (about 1 inch). If yours matches, it’s likely correct.
• Air filter cover included – but verify the cover shape matches your air filter housing (some early 104M02 engines used a different cover design).

Key Things to Know

• Aftermarket quality: This is a non-OEM replacement. Expect basic machining; may need minor adjustment to the idle mixture screw (factory setting is usually 1.5 turns out from lightly seated).
• Installation difficulty: Moderate. You’ll need to remove the old carb, swap over the fuel line and governor spring, and reinstall. Watch for the small gasket between carb and intake – it’s easy to lose.
• Common gotchas: The included air filter cover may not seal perfectly on all 104M02 variants. If the old cover fit better, reuse it. Also, the fuel inlet fitting may be aluminum and can crack if over-tightened.
• No primer bulb included – your engine likely uses a primer bulb on the air filter housing, not the carb itself.

Should You Buy It

Buy this if you have a 104M02-series Briggs engine with a bad carb and want a cheap, functional fix for a mower or small engine. Skip it if you need exact OEM fitment or a long-term heavy-use repair – the quality is adequate for occasional home use but not commercial duty.
