How to set up my STS engine
 

I am new to the sport and have just completed my first car. I have run my STS 12 engine in with about 5 tanks of fuel. My problem is that the engine came with no info on how to set it up, at present if I release the throttle the engine shuts down. Can anyone either tell me how to adjujst it so that the car can sit there idling, or can soemone point me at some online info for setting up my engine.

Thanks in advance
