It was working fine until I heard some kind of knock, and then this happened. And I didn't hit a rock...
I'm sorry to hear about these low speeds though! What engine is it? Perhaps there's some lock on it that restricts revving in neutral gear, and that now is coming on (faulty) even on forward? I found one of those on my engine, but I didn't have that problem. I just thought it could happen. Can you go as fast in reverse as forward? :o
