If you have some experience with taking the top of the carb off you can inspect the float needle valve. Do you have a book displaying all carb parts? Any buddys who have carb experience? It's really simple once you know how to get the top cover off clean and carefully. If the float valve is not working right you will find fuel coming out somewhere on the carb, could be at the butterfly on the bottom or just on top where there is a vent for overflow issues. If you replace the float valve the spacer must be the exact size of the one that came out to keep the float at the correct level. Let us know what you discover...
