It is likely you got the deal on the thread because it was old and on its last legs. It should not have been sold even at a real discount. Old thread is a night mare to work with. Unfortunately there is no way an inexperienced eye can spot old thread until it acts up in the machine. An experienced eye might be able to but even that would take some doing.

I trust you will have luck with the heavier thread and the larger needle.
