Just to let you know you are never supposed to use partial carb heat. Carb heat is used to melt carb ice and expel it. If you use partial carb heat you run the risk of melting the ice at the front of the carb but allowing it to refreeze at the back of the carb which will cause an engine failure. Also there is no temperature gauge associated with carb heat. You will see the engine start running at a lower RPM with a slow but constant loss of rpm. Also you can tell that you had carb ice if the engine sputters a lot after engaging the carburetor heat. Leave the carb heat on for about 30 seconds or so and cycle it as needed.
