You can try contacting Sears and see if they can track one down. It doesn't show one on searspartsdirect so you might need to actually get the numbers off the carb itself. You can search "Snow blower parts" and then one by one try the different parts companies with your model number to see if someone has one. There is a very helpful forum, snowblowerforum dot com that you can post the question on and might get someone with a similar model or more craftsman knowledge who might know where to get one. If you get the numbers off the carb I'd also check out ebay as at times the carbs are so cheap rebuilding them doesn't make $$$ sense.
