Have a 2009 FD 70 not floating properly. Have changed vertical rods over to eyelets a couple years ago. Lately header wont sit right on adapter. When locked up it's level but when unlocked it sits uneven when you lower it and lift it back up. Right wing doesn't want to drop down sometimes when floating down the field. Acts like it has a catch in it. So I put new needle bearings in the bellcranks on both sides but that didn't help. Now am wondering if there is something else to check why it doesn't sit level on the adapter and why that wing acts like it has a catch in it when going down the field. Thanks.
