You can't use someone elses needle settings to judge yours, they vary too much, it sounds like you haven't peaked the highspeed needle yet. To do this, run it wide open and turn the highspeed needle in about 2 clicks at a time, Saitos do not respond instantly to needle changes, give it a few seconds to stabilize then in a couple more clicks. At some point the rpm will change suddenly and dramatically, when you get to 9,000 you be close. Do one click at a time from there, at the slightest hint of a rattling noise richen a couple of clicks.
