hey John, No dont richen anything yet.. You need to complete the break-in with the settings that came from the factory. Then you will tune the engine to suite your needs(Usually a lean setting). and the LSN should be tuned to hold an idle, and when you pinch the fuel line going into the HSN it should take about 7 seconds for the engine to die, it will rev but it should quit in about 7 seconds. Its normal to rev before it does quit.

You will find the N-Tune tuning dial helpful. They are located @ [link=http://www.rchardware.com/]http://www.rchardware.com/[/link]. The price is right and they are such an incredible help while tuning.

Hope this helps some.

Good luck and Have fun!!
