Did more adjusting and it seems if you leave the motor mounted loose its able to slide in the slots and center it self pretty well. I ran it at 90 deg. and 45 deg and it seemed to start stop and raise the blade good. I think the slop in the mounting is what it needed,when you bolt that motor tight it binds it all up.

Let me know what you were thinking afx but I think its good now.

One might just be surprised how many of that saw design is set up new without the owner observing the instruction manual and leaving that pivot cap screw tightened. Then their saw doesn't work right and the next thing it's for sale for cheap.
That screw is usually a special with some provision to prevent movement like vibrating out. Possibly nylock or similar.
