Most likely the blade, little else to go wrong with them really unless the main head pivot is excessively worn. The blade should have reliefs on alternate teeth at an angle of about 45 deg. This creates the set on the teeth on these blades and keeps them cutting straight and true. It could be the spindle bearing worn but i think you would know about that, as it would feel horrible. Give it a wiggle and see if there is any excessive play.
You are talking about it being out of square in the vertical plane?
Kind regards,
Scott

its out of square in the vertical plane it didn't bothered me before but i tried to cut a merge collector & end with a big hole in the midle i thought that i measure something wrong & made another with the exact same hole in the midle so after a mechanics square i'm 1.5 mm off x 8 cuts here is where he hole came from
thank you for the reply scott,the blade is ok as is the spindle bearing the pivot looks to be tight with no play at all but if this is good too the castings are bad & noone in the last 50 years notice it

I might be the camera angle, but it looks slightly off...
What i find on our one at work, (A Thomas, but different version) is the gap where the blade goes through is quite wide, so as you pull the blade down, the workpiece tilts up slightly. Especially if there is play in the jaws, allowing it to lift as it tightens, or whatever is being cut to move slightly.
Not a problem if its supported on both side, but noticeable when cutting say, 10mm off the end of a bar.
