just casually it seems to me the double whammy of thick syrup and extreme swings in air temperatures might make any syrup feeding system a bit more complex than some here seem to suggest. matter of fact I wouldn't be surprised to find that given the nature of syrup and low temperatures that on occasion plugging of pipes might be another issue untouched by anyone's comment here.
