It does have jets inside on the metering block on both sides of the power valve, along with holes that appear to be for jets. I bought the carburetor new so those are whatever came on the carb. And I don’t know what those do.


Those are probably the emulsion jets. The idle feed restrictions will be in the upper corners. Maybe post a picture of your metering block and someone will show you what is what.
