That's true, if the carb is clogged, the engine will run rich and the engine will get hotter, no if it started good the first time you looked at it and it's been sitting for over a year, my best bets are the carbs need cleaning and it's along time for fuel to sit there, clean the carbs and I can almost promise you it will be fine, but I would check over everything aswell, change water coolent, and give it a full service, check all hoses bla bla bla and will stop any future problems
