Does anyone know how to adjust this saw?

I'm getting 3/100 runout at the arbor and 7/100
runout at the edge of a 10" blade.

I've spent a lot of time adjusting the rear pivot
bracket but I can't see this actually doing anything.
The bracket only moves about 1/8th inch.

The blade has a very visible wobble to it with
the runout. What problems will this cause?

Thanks

Ken
