I finally got my raptor's carb cleaned out and started after sitting for two years. It is running fine and idles, however even after I shut it down and turn the fuel off it is leaking out of drain hose from bottom of carb. The screw for the drain is tight and throttle is not stuck open. Any ideas why this is happening?

 

the needle and seat in the carb need replaced or ther is dirt, rust unnder it, after you replace it keep Seafoam in the gas 3 or 4 times a year and turn the gas off when not in use
