I've got a mid-90's 1845c. Had to also cleanup my AUX valve spool spring -- the cap was full of garbage and corroded. I usually only use AUX for 2-way my snow plow and works as it should (or good enough). But when I tried to run a small rototiller attachment (rated for my 1845c's flow rate), I couldn't get full flow out of the AUX unless I evvvvvvvver so slightly bumped and held the boom-up handle (left-hand handle). It's a night & day difference with & without that handle bump. 🤔
