This aftermarket snap-in primer bulb is engineered as a direct cross-reference to Walbro 188-512 and 188-512-1 specifications. The snap-lock base allows tool-free installation — simply press into the carburetor primer port until seated. Compatible with a wide range of outdoor power equipment including Stihl chainsaws (MS series), Husqvarna units, Echo trimmers, and Poulan equipment using Walbro carburetors. Fuel-grade silicone/rubber blend resists swelling from modern ethanol-blended fuels. Each unit includes integrated check valve.
