beware of AGM engines bought on e-bay, I bought an AGM 30cc from borantrading, an e-bay co, It was advertised with a USA warranty, I have a problem with this engine and I contacted AGM, they refused to service my engine, they said the warranty was good only for engines bought from their web site, they wouldn't give me a phone number or service center address, the service centers shown on their web site told me that they were removed from warranty service, the e-bay company said ,Sorry,
