Hey all. I have a 4000-ish hour 742 that sat abandoned for 25 years before I bought and re-powered with a v2203DI. Wonderful machine except for one issue. Slow pivots with just a little bit of forward left and no right or just a tiny bit back right is super jerky. But only when I am stopped or slow back on right drive. Forward slow is fine. Slow back is fine. Slow left hand pivot is fine. Only when I try to feed in a bit of forward left when right drive is stopped or slow back to I get jerky motion. It worked fine all winter with chains and snow, but now seeing on dry terrain. How can I further isolate?
