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? |

I don't run carbs, so arguing about idle mixtures with carb guys is a waste.
Idle adjustment on an L-jet is very important. It is the starting point for the fuel curve. My L-jet #'s are: Idle 14:1 Acceleration: 12:5-13.5:1 WOT: 12.5 Cruise on hwy: 15.5-16:1 If I richen the idle numbers, the rest will follow. I would like my idle to be around 13:5:1, but if I do that my WOT goes into the 11's. So I always work on getting the curve right and then adjust the idle after that work is done. It will take a couple of tried to get it where you want it. I have 2 AFM's. One set up for road trips (leaner for gas mileage :31mpg) and one set up for racing (richer : 22mpg) I read this 5 times before attempting an adjustment. Lots of info. http://www.itinerant-air-cooled.com/viewtopic.php?t=7761 |
