No! That is a breaking procedure for ABC 2-cycle engines. To break in your Saito, turn the HS needle out about 4-5 turns (very rich). Start the engine and let it run slowly, only about 4000 rpm. Use a tach, you can't judge the rpm's of a 4-stroke as easily as a 2-stroke. Keep the rpms low! After a tank has gone through it, lean it some, maybe to 3 turns out and run another tank through it at 4000 rpm. After that adjust the HS needle to run well and go fly it. Keep it a little on the rich side for maybe a dozen flights or so. Adjust the LS needle as needed for a good idle and smooth transition.
