Thats good,,, that means you have a good seal on the manifold and carb flange,, You are pulling alot of air thru, and when it mixes with the fuel, it cools it considerably as it passes thru the carb. A good grade pump gas will sweat, or frost the manifold,, E85 will freeze it,,, When tuning,, you have to make sure that frost is gone,,, sure it can sweat, but not frost,, the reason is, on the track, it wont stay frosted up as engine temp rises from a cold start. Cold is always good,,, hot air, dont make power,,, a fuel that is colder, like E85 can help maintain the colder temp in the intake and hold the power longer until the manifold heats up,, or you could wrap insulation around the carb flange and take advantage of the cooling effect. Id say you need to put some time on the engine, go out for a long drive, put a bush hog on the back and mow for a day or two, just any kind of work to put a load on the engine for a while. It will wake up in a few more hours,, just keep an eye on the heat guage, and the spark plug color under a load,, if it runs hot, under a load, check the plugs for color, if they are white, or very light in color, richen the main jet and see if the temp goes down, if not better check the water,,, LOL! Put some time on her! At least a good 5 -10 working hours,, listen to it,, watch the plugs for color,, Chad
