Loosen the three 1/16" flat head screws on the back endcap of the motor.
Look to the back edge of the motor to the orange or blue colored ring... you should note some slots on that ring.
Take a small flat head screw driver and rotate that ring clockwise to reduce timing, and counter-clockwise to advance the timing.
Please note that the ring can only be adjusted so far and then it will stop...pushing harder will not advance the timing more... it will just break the timing ring!
You know when you've advanced as far as you go when the slot nearest to the motor solder tabs tucks up right next to the tab.
Hope this helps!
