I have been working on getting this motor running good. I actually was in the process of tuning, when the carb starting pissing out fuel. When i traced the leak it led me to a open hole under the carb right between the butterfly and bowl. I have a couple other TN-26's in the attic. While looking at these i noticed the carbs on all of these models have this small hole. Does anyone know what i'm talking about? This porblem would lead me to believe the float is shot. Second opinions with people with knowledge about this model would be hlepful....The only reason i am hesitant, is the carb hasn't had issues half way through this process, and all the sudden it started leaking.
