Hi Harry, as I said my experience is with Diesel 454 and 495. I feel your pain with the loader on the 454, there is not much room to work on any of the engine parts. My brother had a 2250 Quick Attach loader on his 495 for a few years. The last 4 cyl gas tractor we had was a 300U with C-175 engine in it and it was cold blooded at -25F, the carb used to frost up and it would spit and sputter and you would have to run with choke part way on until engine got warm and carb stopped icing.
Re gas and ice, I don't know where you live but in Canada it has been common practice by the oil companies to put 10% ethanol in the winter gasoline for several years now. The ethanol combines with the water and eliminated the frozen gas line problem of course unless there is a large amount of water in the tank.
