The carburetor prepares the fuel-air mixture for the 2-stroke engine of the Oleo-Mac chainsaw: it meters fuel and air depending on load and revs. Carburetor for the OLEO MAC 937/GS370 chainsaw, for EFCO137/MT3700. Country of origin: China.
Replace it if the saw starts poorly, stalls at idle, does not pick up revs or floods, and cleaning and a repair kit have not helped. Carburetors of different models are not interchangeable, so check the saw type.
