ABSTRACT:
An engine decompressor includes a decompressor pin provided through a pin hole on the surface of a valve cam, a decompressor pin operating shaft in an oil passage provided in a valve cam shaft of the valve cam for vertically moving the decompressor pin by its rotation, a fly weight rotatable by rotation of the valve cam shaft so as to rotate the decompressor pin operating shaft, and a thrust receiving plate separate from the fly weight for restricting the axial movement of the decompressor pin operating shaft in the oil passage. The engine decompressor is capable of operating a decompressor mechanism normally even if the lubricating oil increases in pressure.
