Static Engine timing 5.7 Carb

I have a 2001 Pro Mobius with a 5.7L Carb motor. The engine was damaged last year during the winter, and i have since bought a new motor and installed it. I need to know the proper way to set the initial timing on the motor. I know that there is a loop-back adapter and im not sure if its suposed be plugged in to set the timing or removed. Right now i set the initial timing to 10deg adv.. with the loop-back plugged in. But i noticed that there is no advance when i reve the motor up to 3000rpm. After i set the timing should i remove the adapter? Also what is good TOTAL timing setting to look for (does 30-32deg adv. sound about right) Please advise...Thanks
