Worth it for contractors who service multiple equipment brands. The Oregon 49-058 replaces 10 different Briggs & Stratton OEM part numbers and fits over 300 engine models including Quantum (3.5-6 HP), Quattro, and Sprint series. At 5 stars average rating across multiple retailers, this aftermarket bulb delivers what matters: universal compatibility that minimizes inventory.
This kit shines for repair shops, lawn service contractors, and anyone maintaining mixed-brand equipment fleets. Compatible with Pulsa-Prime carburetors across walk-behind mowers, pressure washers, tillers — the workhorses of Montana’s short mowing season.
Universal Compatibility Beats OEM Every Time
Replaces 10 different Briggs & Stratton OEM part numbers including 494408, 4128, 4178, 5084D, 5084H, 5084K, 691347, 694394, 496115, and 694395. That’s inventory simplification at its finest.
Stock one part number instead of chasing down specific OEM versions for each engine model. The detailed compatibility list includes over 300 models (e.g., 093902, 095902 series) spanning the entire Quantum lineup from 3.5 HP walk-behinds to 6 HP pressure washers.

Oregon 49-058 is considered a high-quality aftermarket alternative that matches OEM specifications. The Stens 120-178 serves as another aftermarket option, but Oregon’s lifetime warranty on all Oregon replacement parts gives it the edge.
Cost-Effective Without Compromising Quality
Oregon 49-058 is considered a high-quality aftermarket alternative that matches OEM specifications. That’s contractor-speak for “works just as well for less money.”
Primer bulbs can wear out or crack over time due to exposure to fuel, weather, or frequent use, requiring replacement. When they fail — and they always fail eventually — contractors need reliable replacements fast. Lifetime warranty on all Oregon replacement parts (Source: Home Depot) backs up the quality claim with real coverage.
The 5-star average rating across multiple retailers tells the real story. Positive feedback includes “Exact fit for B&S 3.5 HP engines”, “Perfect fit for Quantum series”, “Good quality material”, “Works exactly as expected”. Zero complaints reported in identified sources.
Procedure summary: Popping out the old cracked primer bulb and pushing the new flexible bulb into the carburetor seat. No tools. No hassle. Tools required: None specified; described as tool-less installation. That’s 30 seconds per repair instead of fumbling with screws and gaskets.
The primer bulb’s primary strength lies in its ability to facilitate easier starting by allowing users to manually prime the carburetor, ensuring the engine receives the correct fuel mixture before ignition. This makes it especially useful in cold weather or for engines that are difficult to start, which is a common concern among contractors who rely on consistent, reliable equipment. Montana’s spring startup season demands reliable priming when equipment’s been sitting all winter.
