(Footnote)
Fuel injection timing is adjusted by changing the
installation angle of the fuel pump.
When the fuel injection timing is advanced for
example at 2 degree, loosen the nuts, which fasten
a fuel pump on the gear case, and turn a fuel pump
body at 1 degree to the outside direction of the
cylinder block. Then tighten pump installation nuts.
And, slant a pump to that reverse direction when the
fuel injection timing is delayed.
