I just recieved delivery of my 751F....can't find any fault other than some play in the left (as you set in the machine) stick. After flipping the ROPS up....the problem is an aluminum 'yoke' (for lack of a better term) that turns the valve on that side....the pinchbolt is tight....but it's still loose on the shaft. As a short term fix, is there any reason I can't remove it, fire up my mill and make a spacer/shim to take up the play? Or, should I just leave it alone and get a new one when my (ordered but not yet here) parts/service manuals arrive. Doesn't look like rocket science.....but I've said that before....and ended up with a large can-o-worms. Thanks! Jim
