P51delta,
Open the HS needle 3 turns. Start the engine and go to full throttle. When at full-throttle, and with the use of a tachometer, turn the needle in slowly until you reach peak rpms. Go slowly and let the engine catch up to the changes in the setting of the needle valve. Once at peak rpms open the needle valve to reduce rpms by 200-300. This must be done only at wide-open throttle. If you adjust the HS at part-throttle you will not be able to properly set the LS and the engine will never run as well as it can.
On Saitos the LS needle must also be adjusted. This is actually done properly with the HS set to peak rpm before you enrich it for the 200-300 rpm drop.
To set the LS: Return the engine to a low (1/4 or less) throttle setting, slowly screw the LS needle in until the rpm just begins to fade. You will have to turn it pretty far, they are very rich when factory-new. The rpm will increase as you turn it in and you will have to close the throttle a bit to compensate for that increase. When you reach the point that the rpm just begins to fade you are now just a little lean. From this point open the LS 1/8 of a turn at a time until the engine will transition smoothly, repeatably, and reliably, from idle to full-throttle. You will probably need to open it about 1/4 (or a bit more) of a turn to get a good transition.
Once the LS is set it is time to go back to full-throttle and reduce the peak rpm 200-300 by opening the HS. It may take only one or two clicks of the HS to accomplish this rpm drop. Again, let the engine catch up to the change.
A Saito will run with the LS left rich...it will not run well. They are not difficult to tune, but the needles must be set in the proper order.
82s are real nice engines. Good luck with yours.

P.S.: The above assumes that the engine has been run-in enough to accept full-throttle operation. If it has never been run, follow Saito's instructions for the proper operation during the first several minutes of operation.
