snow thrower will not KEEP running
I have a Craftsman 5 horse dual stage snow thrower. It has been running and working fine the past several days. It now will not keep running. I push the primer a few times,use the electric start, it runs for a few seconds then quits. I disconnected the fuel line at the carburetor, fuel is present. I pulled off the muffler, no blockage there either. I pulled the spark plug and cleaned it, looks good. I don't get it, it was running fine. Any suggestions?
