OK.... These generators are made by Lifan. That is the secret.... Other companys put these stickers on them that change their name. Sometimes it is called Wen or Power Pro. I spent a month searching for "Chicago Electric Generator Parts " And just like you found nothing. I needed a Voltage Regulator and found all the parts for these things at this web site... http://xmcparts.com/voltageregulatorpart35.aspx
