I have a 790E that the bucket function works slow sometimes. If you put a load on it with the stick it will then only move very slowly. If you wiggle the control back and forth rapidly it will then start to work properly. I don't think it is a sticking spool. Does anyone have any experience with these machines. My suspect is that it may be a compensator valve sticking or a shuttle valve sticking. Has anyone had any experience with this problem........................................... .............................................
