I first checked to see if it needed gas , and then added some from the gas can I keep in the garage . Now that I was ready to mow , I put on my work gloves , and rolled the mower outside . Then I opened the gas flow on the engine and then shifted the throttle lever to the bunny rabbit setting , for full . I moved the throttle lever down to the work setting and shifted the blade lever to on , and started mowing . I started right in front of the house , making a big circle to border by the street . I was sure to mow so I was facing oncoming traffic , because my house does n't have a sidewalk . I moved it aside , mowed that patch , and then the front lawn was done . I took the mower back into the garage , closed the gas flow lever , and then went inside and had a lemonade . Question: When did the mower start up? Option1: after he opened the gas flow and shifted the throttle Option2: it didn't
