I think he said carb kit not entire carb, I just went to 5 different web sites and none of them are showing a p/n for a carb kit or needle and seat kit, I would just try cleaning the carb out good and reinstall first, there may just be a piece of something stuck in the need seat. And as I said earlier a shut off valve will take care of the problem also for about $5-6 , carb will cost you over $100 I'm sure.
