Before going any further you will need to install a clear fuel filter between the fuel pump and the carb inlet. It doesn't have to be an expensive one. You can just get one from W-mart G-2 model or smaller as long as the tube connections are the same size as the your existing fuel hoses. After installation, do the regular starting procedures, i.e. pump the primer bulb, put the control lever in fast idle, push-in the key for choke and start the motor. Observe the clear fuel filter make sure it stays full or at least 3/4 full. If the motor dies, report the status of the clear fuel filter.
