My machine is less than one year old and upon the fourth time I used it, the engine stalled a couple of times and finally wouldn't start. I couldn't pull the cord out anymore. I took it to the dealer and he said he got some gas out of the carburator bowl and claims I had no oil in my gasoline. This is simply not true. He claims the engine is seized because of it. It's now a case of he says, I say......I still the have the fuel mix I drained out of the tank for safety purposes since I was taking it to the dealer in my car. The gas clearly has oil in it..... I called Toro today and was told to call back on Monday and speak to a supervisor.... Hoping that Toro backs their product.
