Hey guys I have a craftsman snow blower 5hp and when it idles gas spits out of the carb its worse on high also when I prime it it over flows out of the carb please help

 

Sounds like the carb bowl float or needle seat is failing, clamp off the fuel line, remove the carb bowl, unclamp the fuel line, as fuel flows raise the float with minimum pressure see it the fuel flow stops, if it stops then the float probably has a hole and is a sinker rather than a float. Have a good one. Geo

 

Would that make gas spit out too wile running Cruz it does not leak out when off
