(Supplementary explanation 2)
When fuel injection timing is advanced or delayed, the
installation angle of the fuel pump is adjusted.
When fuel injection timing is advanced for example at
0.5 degrees(cam), loosen the nuts, which fix the fuel
pump on the gear case, and turn the fuel pump body in
the inside direction of the cylinder block at 0.5
degree(cam), and tighten the pump installation nuts.
And, when fuel injection timing is delayed, a pump is
turned in that reverse direction.
