In what you are describing you are approaching the problem in the best manner. As long as there is a plug in the tube you are unable to pig. Once there is a open passage through the furnace pass and a positive water flow has been established then pigging can commence. To remove the tar from the pass once the plug has been removed an option is to steam the unit out before pigging.
