I agree with houston
1. Warm up the engine
2. Turn in the LSN 1/8 of a turn
3. Bring the vehicle to a stop, count to 5, then floor it. You should get immediate acceleration with smoke from the pipe.
4. Bring the vehicle to a stop. The idle should settle down to normal. If it doesn't, continue to lean the LSN 1/8 turn until you get good throttle response and consistant idle.
Good Luck.
