Has anyone that lives up North figured out how to install an engine block heater for the Uforce machines yet? Self-adhesive oil pan heater won't work because the bottom of the oil pan is ridged and not flat and a lower radiator hose heater won't work because the lower radiator hose doesn't climb upwards enough for the heater to work. I live in North Dakota where we have below zero temps for the majority of the winter and my Uforce 600 doesn't like to start when its -25 out. It will eventually start but takes 2 or 3 times for it to stay running and I know these extreme cold starts are bad on the motor. Thanks
