#4 cylinder would eventually get hot with the bike running on three anyway. Your hand probably can’t tell the difference between 350 degrees and 180 degrees. Fuel in float bowl is no indication that slow speed jet is not blocked. See if you can remove the float bowl with carbs in place. Then you can get at the jets and either spray carb cleaner up through them with some spray straw gymnastics or unscrew them and clean. I can’t remember whether the carb bowl screws are accessible or not on your bike, Graham
