Snow Blowers

I purchased a Husqvarna 27 inch snowblower January 2015. I have less than 20 hours of running time it. It seems to be well built and it runs OK. It has a pull start on it and an electric start you plug in the wall. I wanted to get it running last summer so I serviced it and started it occasionally. I noticed that when I placed the settings as suggested in the manual an pressed the starter it seemed as though the starter would run but it did not engage the fly wheel (I believe this is the way it operates.) So now the starter will run but the engine won't start. And when I pull the rope it doesn't start the engine either. I walk away from it come back a day or two later, push the start button it will turn over until the next time. Then it is the same thing all over. I called the place I bought it it seems like a catch all answer to all lot of problems is traced back to ethanol in the gasoline. I have to travel 75 miles or pay $ 109.00 for a service call. I am not sure what to do.
