Decompression Valve 001-131-150

This authentic item is supplied by the original manufacturer for use with Makita chainsaws and power cutters. It is an identical replacement for a missing or a faulty decompression valve that was installed on a new unit. This valve helps to make starting easier. Depressing it reduces the force needed for compression, so little force is needed to accelerate the engine to its starting speed. The high pressure in the combustion chamber after the first ignition automatically closes the decompression valve (button pops out). Please make sure to refer to the owners manual and the appropriate diagrams of your model for the correct location and application of this component. Keep in mind this high-quality valve is made of durable metal and is sold individually.
