it has been SO long since I've dealt with anything but carburetors on the 1760 that I can't remember....and I don't forget much on mowers.
Come to think of it I can't remember if I ever even put a belt on them? 1460/1560 plenty but I don't recall doing any 1760's. I think they're similar, and easy. You gotta remove part of the steering (drag link) but the rest is easy and it only goes on one way.
