Could anybody provide a parts list or drawing (assy,exploded isometric) of the float portion of the control valve assembly for the LA680 loader? My float does not work. Bought the rebuild kit (I can't believe how much that is for a bag of springs and ball bearings!). But upon taking everything apart I think the problem is somewhere else. Everything inside looks fine but won't "mechanically" go down far enough to get the balls to detent? I bought the machine used and it has never worked so I'm thinking I have a spacer missing or in the wrong place - preventing the machine "shuttle" from moving down far enough inside the valve. Any help appreciated - drawing or parts list would be awesome. Manual is useless. Thanks
