What Jim said!
Best thing you will ever do is buy a new blade from Tuffsaws. If you need advice, just give him a ring and he'll sort you out. His blades are superb and will transform even a cheap bandsaws, they aren't overpriced and usually delivered quickly. (I don't have any connection btw, just a satisfied customer).
Next you need to spend a little time setting up your guide so that cuts are parallel to the blade some are simple others less so, my Startrite 352 has to be shimmed for example whilst yours might be a couple of bolts. Here's a simple video but note that you should check your setup whenever you change blades. This is a necessary maintenance routine as every bandsaw will drift, doesn't matter what you buy, it's the nature of the beast.https://www.youtube.com/watch?v=IZThUPOr_Ug
