Was wondering what you all use to unfreeze / prevent a carb from freezing up during really cold nights. This morning was second time that the Edelbrock carb linkage was frosted together. The first time it broke free pretty easily, but this morning I had to break out the carb cleaner and give it a shot to free it up. Here in southern Ohio, I'm sure this will be a very rare occurance. I know I don't have any water in the tank, but will go ahead and put in a bottle of gas line antifreeze.
