I purchased a chinese youth wildfire atv model wf150-Q2 for my sons christmas present.  Chain keeps breaking. Dealer we purchased it from says its fixed but its not. Now its sounds like its missing a tooth on the gear but they insist there is nothing wrong with it.  I have tried taking it to another dealer who sells brand name atvs and they won't touch it.  Is there a certified mechanic in the tampa bay area that knows about these machines that can give me a second opinion?  The machines are garbage and I want my money back.  Never had trouble with our honda or polaris.  Theres only one dealer in the tampa bay area that sells the wildfire atvs, and it was purchased from them, so you can imagine why I'm having trouble getting a second opinion.  Everyone in the my area knows there junk but wont back it up in writing.  Please help
