This Craftsman has an issue with the mower deck blade belt. I have a new belt installed & it is too loose, blades do not get up to speed, same as the old worn belt. I have the belt routed correctly and all pulleys seem fine, I tried adjusting the front support so the deck is further back which gives better tension but now the deck is not level & I have to cut in position 4 or 5, it's like it's the wrong belt for this 46"Deck, any suggestions?

I ordered the belt by the part #.The belt I ordered is the same size as the old belt, the mower was doing exactly the same thing with the old belt. I ordered another belt, by the part #, from a different vendor, it’s the same size

You mentioned the belt is routed correctly (you've verified this from the manual or some diagram of how it should go?), so next up is looking at the tensioner pulley, that it can move freely parallel to the belt path, can't move much in the other direction, and that the spring provides good tension (depending on the setup, this may be adjustable).
Tensioner pulley moves freely and seems to be fully engaged when lever is moved into position
