I borrowed a AF meter from a friend and was wondering what is the best process for reading and setting the mixture.
Can I take readings at idle and hold the throttle at 3k and take another reading or do i need to drive it with it under load? based on readings which adjustment do I move first static or dynamic? |

Drilled hole in the TB and had noticeable improvement on idle.
got numbers as follows for AF ratio Accel. - 12.4 - 13.7 WOT - 12.1 - 12.7 Cruise - 12.6 - 13 Coast - 12.9 - 13.3 The cruise isn't as lean as what I have seen is desired. So which adjustment do I go about to bring that in line? Static or dynamic ? I have not moved the mixture screw on the outside of the meter yet it is set 4 1/2 turn open. Idle numbers are still all over the map cause now it won't come back down off of idle Unless you load the engine and pull it down that way, so it idles around 1200-1900 rpms At around 1200 I am seeing 14 |
