I bought a 6.5 HP Toro self-propelled lawn mower last year.  Recently my son said it wouldn't start.  Later I started it with no problem, but later it wouldn't continue to run.  It would start but not keep running.  I called the Toro dealer since it was under warranty and he knew immediately what the problem was.  He said it was the gas I was using, that I can't store gas.  I should only buy enough to fill the lawn mower each time I need to fill the tank.  He was willing to repair the mower, but it would cost half the original price.  None of this makes any sense to me.  Since he was so familiar with it I asked if it was a recall situation and he said no, it was the gas available in this part of the country (VA).  I am having a friend look at it instead of paying them so much money.  Any one have any other ideas?
