I went to get my 8n back in business today. It has been down for about a year. I had to put in a new battery. It cranked over fine. I chocked it for a while and unchocked it, when I realized that gas was pouring in a good stream from the bottom of the carb. It does normally leak some if I over choke, but this time it just continued pouring. I finally turned off the gas valve and it kept streaming out until the carb was empty. Any thought about what the cause might be would be appreciated. Cracked carb? Cracked gasket. Needs carb rebuild?
