JD410 won't start.

I have a 1984 JD 410. I bought it about a year ago for a homebuilding project. Engine hours are unknown. I was able to use it all last summer and into the fall. It would not start without a shot of ether when the temperature dropped below 30 degrees. This winter, I would go out to the land every two weeks or so and run the block heater, give it a little ether and start it. I would run it long enough to get it up to operating temperature. About six weeks ago, it would no longer start....
