I have a '75 Evinrude 25hp. I rebuilt the carb using the Sierra kit including the float and replaced all the fuel lines with the proper hoses. I set the float accoreding to the instruction. It started but after running for 10 sec. stopped. I was able to restart a number of times but it dies after a short time. I looked at the carb where the choke butterfly is and there's a lot of gas dripping out. This is the same problem I had before I rebuilt it. Then, if I waited for a day or so, the motor would start right up and run without a problem --most of the time. I'm not sure what to do next.
