I am trying to figure out a symptom on a MF250 with cold weather starting. At temperatures below 35 or so, it does not want to start when cranked. I have replaced the thermostart and confirmed its getting hot. I have a new starter switch. When I turn key to run, there is also what appears to be a spring resisted position before the crank position. If I apply the key to the springloaded tension (which I understood was how the thermostart works) for 30 seconds to a minute, I frequently have no starter response (no cranking not even a clicking from the solenoid). If I let the tractor sit for a few minutes, it seems it will crank.
Is there some trick to using the thermostart?
