At start up and at idle, it makes little difference if the airbox or pods are in place. The upper end of the rpm range will show the lean condition caused by pods or no air filters and not so much the pilot or enrichener circuits. If there is gas in the bowl, engine vacuum will draw this gas in if the pilot jets are clear. Did you install new pilot jets? In any case, running pods on Teikei carbs isn't a great idea as larger pilot jets or main jets, for that matter, are hard to come by. They can be had but the jets in a jet kit are stock size and won't do well with pods. I would stop looking at the carbs for the time being and look at valve clearances; sounds like there isn't any.
