quote Mike Stroz:
Ok, I’ll look it over this weekend and see if it has a thermostat. If it does have one, I’m going to assume it’s stuck based on the corrosion on the rest of the motor. Is it ok to just remove it entirely?
If it has a thermostat and you leave it out, the motor will not warm up. This will cause rough running and spark plug fouling. If it is supposed to have a T-stat, be sure to put one in.
