It seems like I might give this a try using plastic from a gallon milk jug, sharpie marker, and a hot glue gun.
Plan B might be to use layers of duct tape to make a "flag" for the arm.
I'm having the problem where every so often, even though it is set at "3", my SQ5000 will surge to full speed for a split second on starting. Not every time, but enough to **** me off.
