Unfazed's suggestion is a good idea anyway and his point about TPS and carb sync is valid, but it doesn't sound to me as though the cause is electrical if using the choke improves matters.
If you'd found a lot of water in the tank then there is probably rust present. The filters in the tank and after the fuel tap should prevent debris reaching the carbs, but water can still cause corrosion in the carbs themselves. I think it would be worth taking them off, cleaning them out and blowing the jets clear.
