Sear GT / 19.9 Rough Engine

I have a Sears GT 19.9 Twin Garden Tractor with a ONAN Engine. It was running great until 2 days a go when I went to move it. It was difficult to start and was idling very rough. I began by checking the points, did not fix. I then changed the coil, this resulted in the engine starting very nicely, but when I would give it some throttle it began to run rough and back fire.
