Walk Behind Lawn Mowers

I have a HU800AWD that has the honda automatic choke and I cannot start the engine. It is full of fresh gas and fresh oil. Is there a way to override the choke because it is not working. I also checked the spark plug and air filter. I am extremely disappointed in this is the failure. I just bought it in June and over the last month it is becoming more and more difficult to start. I would actually like to return the mower and get something more reliable. I had a 13 year old Toro with duct tape all around it and it started every time with out a problem. I purchased your mower because of the rave reviews I saw online. I now would like nothing more then to have that old mower back because the choke was assessable and easy to use. If you have a model with a choke not "built in" I would be interested in it. I an extremely unhappy disappointed in my purchase of your product. Please let me know how I can move forward returning this product.
