AT IDLE who cares if the metering rod pistons are bouncing up and down. Nothing is being drawn thru the main circuit, they can dance an Irish Jig all day long and it won't affect IDLE mixtures.
Heck, pull them out and see if you notice a change at all.
Now if we were on the cruise circuit tooling about, yeah, but Idle no.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
