Have you squared the fence to the blade/table. If the table is true to the blade, your mitre slot should also be. You can then squre your fence to the
slot

These lightweight saws can be somewhat problematic in this respect. They have a tendency to come out of adjustment as they are moved about.
First, make sure the blade you're using is true and has little runout. You can check this using a micrometer, or simply marking a tooth and spinning the blade by hand (power unplugged) to see if the blade runs true or wavers in its path. If the blade is warped or bent the problem is probably there rather than the table.
Second, check to make sure the fence is properly adjusted, parallel to the mitre slots. If the fence is out of adjustment, the path of the material relative to the blade will not be parallel, and this can cause poor cuts.
Third, hope it's one of the first two. If not, set a day or weekend aside to work on the saw. Get some good light and flip it over on a table or horses so you can see what you're doing. Have the parts diagram and owner's manual on hand.
You'll need to loosen the bolts that hold the table top against the saw mechanism beneath the top, and shift the saw relative to the top in the desired direction to correct for the out-of true path of the blade relative to the table top. On some lighter saws like yours, this entails re-adjusting most of the saw mechanisms to run true, as they are frequently independently bolted to the underside of the table and not unified construction that moves as a single piece.
You have to shift the saw slightly in the required direction, check the runout of the blade, then repeat until you get it right. If you're skilled and you don't mind standing on your head, you can do this with the saw in position.
There are many excellent articles online that detail this procedure if you search google for "table saw tune up", so I won't elaborate on the details. Try to find one that has a saw similar to yours as an example. Good luck.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Check to make sure the arbor set screw is not loose. The bearings may have shifted when you moved it. I recently rebuilt an old 66. Repositioning the bearings and tightening the set screw could be all it needs.
