Metering levers are set. They move up and down but they do not self adjust. The height is set manually. Just because something moves up and down does not mean that it self adjusts.
Good to see you have a fundamental understanding of it and MTronic. Now re-read my post - I said nothing about the MTronic adjusting the metering arm. I said it adjusted the 'metering' - as in the fuel via the needles, to compensate for what I was MANUALLY doing to the metering arm. You were busy trying to prove your point, and likely couldn't be bothered reading in to someone else's. That's cool, it's the internet, you're entitled.
