Walbro

What Walbro does

Walbro is a 75-year-old (founded 1950) global manufacturer of engine management and fuel systems for small engines, headquartered in Tucson, Arizona. The company's product portfolio spans carburetors (float, rotary valve diaphragm, butterfly valve diaphragm, stratified scavenge), electronic fuel injection (EEM) systems, ignition systems (flywheels and modules), fuel pumps, multi-layer fuel tanks, throttle bodies, filters, level sensors, and starting systems, complemented by high-pressure aluminum die casting services. Walbro supplies Tier 1/Tier 2 OEMs in outdoor power equipment, recreation and marine, and two- and three-wheel vehicle markets, with named enterprise customers including Polaris, Honda, Kawasaki, Mercury Marine, Harley-Davidson, Arctic Cat, Husqvarna, and Deere & Company. The company operates ISO-certified manufacturing and engineering facilities in five countries (United States, Japan, Mexico, Thailand, China) with a workforce of 2,300+ and cumulative shipments of 400 million carburetors, 100 million ignitions, and 2 million multilayer tanks.

The business model is primarily OEM-embedded hardware sales of fuel system components, supplemented by an aftermarket parts channel that distributes through a Central Warehouse Distributor network and a recently launched direct-to-consumer e-commerce storefront (shop.walbro.com). Pricing is unit-based and not publicly disclosed. Walbro has undergone repeated ownership transitions: TI Group (1999), Sun Capital affiliate (2007), Carlyle Japan (2012), a Landon Capital Partners and Nova Capital Management partnership (October 2021), and most recently Overdrive Capital LLC, which acquired the business from First Brands Group's Chapter 11 bankruptcy for $50 million in March 2026, preserving approximately 600 jobs. The CEO is Matthew G. Riddle. Technology differentiation is anchored in proprietary ethanol-resistant spiral metering diaphragms, multi-layer fuel tank construction, and the EEM electronic fuel injection system designed to meet EPA, CARB, and Euro IV emission standards.
