I bought a box full of Holley parts. I was planning on building another 750. In the box is an aftermarket metering plate made by Weber. It appears to have external jets. Can anyone give me any info on it? I might try to use it but would like to know a little more about it. Thanks.

Those jets look like the ones that I have in my Weber 44 IDF carb. You can change the jet, emulsion tube, and air correction jet. You also have the idle jets you can change. Makes the carb much more tuneable that your standard holley.
