(6 Pack) 496115 694395 Primer Bulb Fits B-Riggs and S-tratton Lawn Mower 5085 5085H 5085K

What It Is

This is a 6-pack of replacement primer bulbs designed for Briggs & Stratton and Tecumseh lawn mower engines. They pressurize the carburetor to draw fuel before starting, commonly used on walk-behind mowers with side-valve engines.

Fitment & Compatibility

• Cross-references: OEM numbers 496115 and 694395. Also fits 5085, 5085H, and 5085K carburetors.
• Engine brands: Works on many Briggs & Stratton (Quantum, Intek, Classic) and older Tecumseh (HSK, HSSK, LV) engines. Not compatible with Honda or Kawasaki.
• Before buying: Measure your old bulb’s nipple diameter (typically 0.25” or 0.312”) and overall length (about 0.75”). This bulb has a 0.25” nipple and 0.75” body. If your nipple is larger, it won’t seal.
• Check carburetor type: Fits only primer bulb-style carbs with a plastic or metal cap. Not for pulse-style or fuel pump carbs.

Key Things to Know

• Quality: Aftermarket; bulbs are slightly stiffer than OEM. Works fine but may require a few extra primer pushes when cold.
• Installation difficulty: Easy (5-minute job). Pry off the old bulb, clean the cap, and push the new one in until seated. No tools needed.
• Common gotcha: If the old bulb’s cap is cracked or missing, replace the entire carburetor cover—this pack does not include caps.
• Pack size: 6 bulbs are useful for multiple mowers or future replacements. Single bulbs cost the same or more elsewhere.

Should You Buy It

Good value for DIYers with multiple Briggs or Tecumseh mowers, or if you want spares. Avoid if you need OEM stiffness or have a carb with a non-standard nipple size—measure first. For a single repair, a 1-pack may be simpler.
