This Walbro SDC 44 A Carburetor is the perfect fit for your McCulloch Pro Mac 555 Chainsaw. It is a genuine OEM part, brand new that was not in packaging. This carburetor is designed for 2-stroke engines and is compatible with other McCulloch products as well.

This product is listed as "Open box" but rest assured that it is in excellent condition and should function but may need a diaphragm kit from sitting on the parts shelf for decades.
