Thanks guys very good info. When i purchased the motor the seller started the motor and let it run. After demo, the seller removed the fuel line and let the motor run out of fuel. Due you think this might have caused the problem, possibly sticking something in the fuel pump or carb. The seller said the tank and hose were brand new. After inspection it does appear new. With a new tank and hose have you heard of many problems,the tank is 6 gallons, somebody said they switched to a 3 gallon and the problem stopped. No sure what it has to do with size of tanks.
