T/CCI’s sister company, Tillotson, is a leader in innovative fuel systems and high performance small engine technology. Founded as The Tillotson Mfg. Co. in 1914 in Toledo, Ohio, Tillotson started as a carburetor manufacturer for the burgeoning automotive industry. In the 1940’s it invented the diaphragm carburetor, which allowed small engines to operate in any position, thus creating the modern handheld lawn & garden equipment industry. Since then, Tillotson has pioneered fuel systems for recreational vehicles, high performance race karts and unmanned air vehicles (drones) and recently introduced its own line of portable electric generators and small engines for the lawn and garden market. These generators and engines feature Tillotson’s latest TillotsonTCT fuel system, capable of reducing emissions by up to 40%.
