So after all this I am thinking about selling my YM2001. It has been a great tractor. It starts very easily and doesn't smoke. I cannot detect any blowby on the breather tube. The rear hydraulics do not leak down while sitting. This winter while the temperature was about 33 degrees, I started it without the help of the thermostart. That is the one thing that I think does not work. It coughed a bit for about 10 seconds and smoothed out. It really was quite easy to start at that temperature. It comes with 2 sets of tires.
I am not giving up on Yanmar. I am looking at a leftover YT235 tomorrow.
Anyone interested? I thought about posting the turf tires separately, but someone might want it all. I also have a Woods M5 rotary cutter I need to sell. I will probably post in the for sale area soon.
