Newbe here, I have been searching the posts and not finding my issue, so here goes, I have a B7200 with a 1630 FEL, the bucket curl works fine, however the lift may or may not work, usually its fine until the fluid warms up which is pretty quick, I have taken the valve apart and replaced the o rings (store bought), and now I'm thinking of ordering the right kit, or replacing it with a new control, just not sure what unit to use, OEM @$750 isn't going to happen, the other things I have checked are fluid, the screen filter, new main filter and fluid etc, any thought or suggestions, gannon works fine at all times
