Lean everything out from 3k to red line, once you get a Target A/F at 13.5. If you run premium all the time advance the ignition to 25 ~ 29 depending on how much it really knocks, you need to listen with a mic. you will have to add fuel if your going to add ignition with it, but start leaning out from 3K to redline by -8 percent that should get you in the ball park.
