It sounds to me like a problem I have had in the past. the carbs were gummed up and the jets were clogged. just had to pull the jets and clean them.
When they get if only a couple of them are clogged then under no load conditions the working carbs will support but with load on there is not enough fuel.
could also be clogged fuel filter on the engine but normally if one is clogged then the other is dirty also.
