Two stroke Engines are a whole new ball game. Their are many types of two stroke engines. Lets start with the weed wacker. Weed wackers have a primer bulb to push so you need to pump it 3 times. Then you will need to push the choke lever in to choke position. Then pull the string until the motor fires. After the motor has fired move the lever to half choke. once the motor has started and is warm push the lever to run and you are ready to go. Chain saws are slightly different because they only have a choke. In their case you must push the choke lever to the choke peoition turn on the ignition switch and pull the string until the motor fires. Then put it on half choke till the motor is warm. When the motor is warm turn the choke off and your ready to go.
