well, I work in the small engine industry now. In NC. At the service schools they tell us to 'educate the customer' that most pump gasoline begins to go bad in as little as two weeks from when you get it from the pump. We are also telling our customers to buy 93 octane gasoline or ethanol free gas if they can get it for their small stuff.
I can understand the part about leaded fuel too- a lot of the older engines didn't have valve seats hard enough to withstand unleaded gas and the lead was a lubricant for the valve seats. The trick is to know which engines and with some manufacturers, it depends on what year, and sometimes which engine had the hardened valve seats in it or not.
Most of the gasoline available around here has 10 percent ethanol in it. I am told that they use the ethanol to raise the octane rating of the fuel. So when the alcohol evaporates you have lower octane than when it came out of the pump.
I do find that if I put 93 octane in the tanks of machines I don't use often I am much more likely to get it to start without a lot of fuss two or three months later.

With Ben, anyway, I can tell! He'll be busy working and I�m handing him tools and he says, "give me that..." and I�ve already got it in his hand or "hand me that....."and I�ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
