So the idle on my car is at 15:1 AFR, and the screws are 2 1/2 - 2 /34 of the way out. I have the metering block over at a long time Holley guys shop, and he was going to enlarge the passages by .003, but they are not where they usually are on these metering blocks. To get to the passages, is it through the brass plugs on the bottom of the block? And if so, it looks like those are not going to come out easily. Where do I get replacements?
And is this what I need to do to be able to richen it up at idle, and have the screws in a reasonable place?
