Bought one for my son 3 years ago. Assembled it and tried to start it but it wouldn't. Waited thru Christmas morning and the cart was well received. Tried to start it again, no success. Contacted familygokarts several times and they emailed me several times with solutions that didn't work. Finally was instructed to remove engine and send to California. Was sent back with rude note saying do not run without oil! Well it never ran without oil because it never ran at all. So I replaced the engine and it still wouldn't start. Removed engine again and carried to local mechanic. After $200 worth of more charges it ran...for about a month then whole engine blew. Has been sitting ever since. Do not buy one of these pieces of junk. Spend the extra dollars and get a name brand.
