I have an older model Rancher. Had been sitting for a while. I took it all apart, cleaned out the gas tank, and took the carb off. Some of the vent lines were plugged, fixed that, the float was also stuck, fixed that.

My problem now is that I have a bad leak coming out through the overflow but the float is not stuck! The valve works, I can blow into the gas intake and manually operate the valve and it does shut off. The float has no holes in it. Why is my float not shutting off the gas??
