Toro 144-4679 Carburetor 43cc 2-cycle Summer

Product Description

The TORO 144-4679 is a carburetor designed for 43cc 2-cycle summer-use outdoor power equipment. It meters the air-fuel mixture delivered to the engine, directly affecting cold-start behavior, idle stability, and wide-open-throttle performance. This unit is configured for summer seasonal operation and is noted as a no-tamp style carburetor, indicating a fixed or non-adjustable fuel circuit. It is a direct OEM replacement part sourced from TORO for use in small engine lawn and garden equipment. Installation is typically performed by small engine technicians or experienced service professionals.

This carburetor is intended for 43cc 2-cycle summer engine configurations found in TORO lawn and garden power equipment. Summer-calibrated carburetors are tuned for warmer ambient temperature operation, where fuel volatility and air density differ from cold-weather conditions. The no-tamp designation indicates the fuel circuit is factory-set without a tamper-adjustable needle, which is common on equipment manufactured to meet current EPA and CARB emission compliance requirements for small handheld engines.
