Obviously, the installation angle of distributor decides ignition timing .The steps for distributor
installation is as follows:
A. Rotate crankshaft to TDC position. Then use a screwdriver to turn the groove in shaft end of
oil pump (refer to fig.3-11).
B. Align the mark on distributor shaft with that on the housing (refer to fig.3-12).
C. Align the flat tongue face on distributor shaft with the groove on shaft end of oil pump.

oil pump.
D. Tighten locknuts on the distributor housing and check ignition timing (refer to chapter 4.
ignition system maintenance).
