These are instructions for the newer model, not that different from the XGK2.
The most important thing to do is pull the wire in and out of the fuel line and put in back in. This can be quite stubborn on the XGKII I seem to remember. The other important thing is to take off the jet and clean and prick it.
If in doubt just pull it apart, and put it back together. They're impossible to break withyour bare hands.
