I have a 5 HP craftsman tiller. It was bought new in 2001. I tilled with it 3 times in 2001. From this point on it sat until this year. I pulled the carburetor off and did a deep clean on it and put it back together. The motor on it is a 5 HP briggs. It would start 3 weeks ago when I would put gas in the top of the throttle and run on it's own. Now 3 weeks later it will start but it will ONLY run when I am spraying a continuous feed of carb cleaner in the throttle. What in the world do I need to do to get it to start and run normal??? I have a funny feeling you are going to say replace the gaskets .........but I guess then the question would be what kind of info am I going to need to get the proper rebuild kit and where do I find this info?
