While waiting on some engine parts I started on the carbs. They were in pretty good shape. Obviously a PO had gone thru them at some point. Degunked em, pulled the jets and cleaned each passage and jet. Then reset the float height. The Carburetor Manual from the XS Society is an valuable source here, great theory, how to and best practices. The left carb had pinholes in diaphragm and the right looked marginal so I replaced them with new diaphragms from JBM. This was a very easy repair especially considering you save about $150 a carb over new slides. Both of the fuel tubes on the left carb were loose so I cleaned and JB welded them back in. Note this is the tube from the fuel petcock and the one going from there to the other carb, not the enrichment tube.
