47-55.1 Landon Carter Weber Carb Tuning

[Jemezcrusher]

There are four ports in the center of the carb. Two have long tubes that run down to the bottom and have removable jets (I think they are jet) The tops of the center tubes are numbered but hard to see any numbers on the inserts that go in them the two outside ones also have inserts in the tubes but are shorter in the bottoms. Not sure if these are emulsion tubes or what. at my altitude, I too expected to have to lean this out as fuel at sea level would be for too great up here. Is the opposite. I pop and bang at 5000' feet in Albuquerque and plugs have no tan on them. There is a guy in Albuquerque that has a carb shop that might be able to point me in the right direction, but I imagine I need to change the inserts in the bottom of the tubes. Threads are kinda tricky as the jet tubes were "set" in place with a punch on either side of them.
