does anyone out there know how the positive stop controller actually works on the tokheim 660 visible pump? ive got all the gears and cranks and the stop lever working but there doesnt seem to be any connection from the controller to the gas in the glass. on my fry pumps the positive stop moves a pipe up into the gas to set the gallon output. if your familiar with this pump im looking for the "A" lever handle, its the one to the right, and outside of the controller head. thanks to all who can help....carl
