Hello! My name is Matthew Christian from Tampa, Florida and on behalf of Expert Village, today I would like to talk to you about how to properly use and maintain a high limb chainsaw. The next step in getting our two cycle engine to start, is to set the choke to the on or closed position. What the choke does is it restricts the amount of air going through the carburetor in order to help the engine start. So next step, close the choke or set the choke to the on position. Okay so we have our machine set to the on position, we have the choke on or closed. Next we are going to prime the carburetor using this primer bulb. Now depending upon how long it has been since you last used it, that primer bulb may be dry or empty. Typically 6 full depressions of the primer bulb should be sufficient. But again if the primer bulb were empty or dry, it may take a little bit more. But simply just press in river bulb 6 times and that should be sufficiently primed.
