If the observed “F” dot doesn’t match the appropriate image determined from the previous page,
we will rotate the timing wheel so that it does.
Compare the location of the “F” dot observed with its correct location. Determine the distance, in
mm, between the two, i.e., how much the “F” mark is off at the flywheel.
For example, say we have a single –plugged engine with a 34° “F” mark.
From the previous page, the timing image should look like this:
Say the actual observed timing image looks like this:
The two images are 4 mm apart. Since each 1° of rotation is 2 mm, the timing is off 2°. We need
to move the observed image down in the window, because we are firing 2° too late, i.e., we need to
advance the timing wheel on the rotor bolt by 2°. This is done by loosening the set screws on the
timing wheel and turning the wheel 2° clockwise. This logic can be generalized into an easy rule
for remembering which direction to rotate the timing wheel:
Step 22: Adjust Timing if Necessary
Wheel Hub
“Rotate the timing wheel in the same direction needed to move the
observed position viewed in the timing window to the desired position.”
