I actually think it preformed better after drilling out those emulsion tubes. (Comparing to other carbs I had in it) But its hard to say because that carb on Grammys CJ came off a gremlin. And I totally gone over it and drilled out the tubes before first fire, and after the rebush of the throttle shafts it was back to brand new specs.
IF you find out your tubes are clogged, as your CJ sits more than its driven its something to do. When the gas evaporates from the fuel bowl it leaves orangish-brown granular debris behind.
Verifying your fuel screws are evenly set and idling. If you see fuel dripping out of the Venturi cluster they are clogged.
