This stuff is coming off today. Going to get some heater hose and eliminate it. Funny you should mention. No matter how you start a car when its cold the coolant is also cold and would not matter lol. Saying that I have no plans to drive the car in super cold weather and probably would not cruise when temps are less than 40 degrees and I think there is enough heat under the hood to keep the carb reasonably warm. The heck with it, this stuff is gone lol.
