Locking Out the
Centrifugal Advance
If you would like to lock out the centrifugal advance
or are converting to a Flying Magnet Crank Trigger, the
MSD centrifugal advance can easily be locked out.
To begin, remove the advance springs and weights.
Next, remove the roll pin from the end of the shaft so
the shaft can be pulled out of the advance assembly
about two inches. Rotate the shaft 180° and position
the stop bushing pin in the small hole on the advance
assembly. Install the locknut and washer to the stop
bushing pin, then install the roll pin.
