Got her running today, the injector lines were clogged, but got it running, no bubbles in radiator, no weird knocks from engine, sounds just like my other 2210.
Now for the issue (did we really think it was going to be this easy?)
I put it in gear and it didn't go anywhere, but after pressing clutch in and letting it out hard it starting moving but I hear a whine in it, drove it in all gears around the yard then tried the 3 point, it doesn't lift, went to ride again now it doesn't move, the hydro fluid is definately contaminated with water after checking it once I got it running, I'm guessing water is the reason for the intermittent working / not working?
Bout to drain the trans fluid and clean screen, post back in a bit.
