i have seen two differnt types of 18R-G crank pulleys.
# with two timing marks (TOP DEAD CENTRE + 12degrees BELOW TOP DEAD CENTRE)
# with 3 timing marks - TDC, 7 degrees BTDC and 12 degrees BTDC
as you stand in front of the motor looking down on the crank pulley, the pulley rotates CLOCKWISE, hence the marks move from left to right. As such the MOST RIGHT hand mark is 12deg BTDC, and this is what you should be aiming for at operating temperature with an idle of around 900rpm.
If you marks are further to the LEFT of the indicator pin (the thing fixed to the timing case) when you use a timing light, then your dizzy is too advanced. If the marks are to the right of the pin, then of course the dizzy is retarded.
Turning the dizzy to the LEFT will ADVANCE the timing, turning it to the RIGHT will RETARD it.
Good luck. One day i will scan in the "Green Book" - Toyota's 18R service manual.
