  If your Grupel Portable Generator won't start, there are several possible causes: * The engine may be out of oil or have a low oil level. If so, add oil. * The fuel valve might be blocked. In this case, clean the fuel bowl. * The engine switch may be turned off. Turn the switch to the ON position. * The spark plug could be faulty.
