hello, so I bought a snow blower off craigslist (a little back ground on seller they sell snow blowers tires anything that has to do with outdoor equipment) I go to see the advertised snow blower and There is no snow on ground yet to really check it out properly. so we let it run and it seems o.k but it only ran for a minute or so as there was very little gas in it (this should of been a red flag to me!! so I buy it "as is" thinking its an old timer it should be O.K BIG MISTAKE!! anyways I bring it home and a few weeks later here comes the 1st storm I start to use it and after 3 or 4 minutes of really poor running and only throwing the snow a foot from the chute it starts stalling. I take it to a repair guy and he goes thru it he does get it to start but as I explained to him it took a few minutes to start stalling he decides to let it run for a few minutes. well after 8 to 10 minutes the machine starts to leak a white milk like substance out of every seem and crack on the engine (which I'm told means the engine is blown) so I call the guy who sold it and explain who I am and which machine I bought and the 1st words out of him are "NO MONEY BACK!!!) he says he will look at it but he really cant promise anything and if it costs for parts I have to pay and pay him to fix it. he never offered me an exchange for a good one or to repair it for free. do I have any recourse since it was sold "AS IS"?
