I would check the fuel supply. Is the tank outlet plugged? It has happened to me several times, with a rag and a cover for fuel line deicer. A collapsed fuel hose? 

I have (2) Hd'6s. They are a great tractor.

I'd check out the simple things mentioned above first, but since the PO has had the pump off I'd check out the timing. Sounds like the timing is too high. Either way, don't take anything for granted.
Yea, I can fix that.....
