Rebuild Your Pullstarter, page 4
With the spring assembly in place, carefully put the starter cord all the way out of the pullstarter housing.
Use the needlenose pliers to carefully put the curled end of the spring inside the plastic C-shaped part of the pullstarter housing in the center of the assembly.
It should look like this. If you've bent the curled end slightly, don't worry about it, just use the Philips screwdriver to widen the curled part of the spring so it is snug inside the plastic piece.
Drop the one-way bearing back into place. Notice the black one-way bearing goes into place as shown below.
Remember that the silver-colored one-way bearing should have the angled edge face the open side of the pullstarter.
For the 15FE, 15SS and 12R SS engines, you can use a screwdriver that has a 6mm shaft to turn the one-way so it will wind up the cord. For our Nitro Star Pro engines you can use the pullstarter shaft that is attached to the pullstarter.
If you do not have a screwdriver that will fit, you will have to use a pair of pliers to wind up the spring.
Once the cord is fully wound, hold the spring assembly in place firmly with your thumb and use the screwdriver or pliers to pull out the cord from around the spring assembly.
Continue to hold firmly on the spring assembly as you pull out all of the cord.
Pull the entire length of cord out from the inside of the pullstarter housing.
Then, pull the cord out of the main body of the pullstarter. Make sure to let it untangle itself.
Wind it up one more time.
Pull the cord out again, following the same steps as above.
Untangle the cord again and take the twists out, then slowly let the cord retract.
When the cord is finished retracting, snap the retainer clip back into place.
And you are finished!
