I have bee all over the net but can't seem to find the info I need

Can anyone tell me the stock adjustments for carb settings on an '88 Jag 340cc? I had to replace the jack shaft bearings. Then it wasn't idling properly so I cleaned the fule pump and want to reset the carb but can't find the proper adjustments.

Did you dismatel and clen the carbs good! Check your jets against the belt cover chart. the chart is usualy a little rich, but good to go by.
