Pull out spout, set base timing to 10*, adjust WOT Spark Advance vs. RPM Function - set to desired total timing 2500rpm+, put spout back in.
Also, you can get by with pulling the spout and setting your total timing. Do not re-install spout. If I were you I wouldn't go above 18* total timing until you know what your air/fuel ratio is doing on the car.
