I believe the problems that some people have with E-10 in their small engines and marine engines are regional in nature. In spite of using Star-tron conditioner in my small engines, I have had to replace several carburetors over the past few years. Typically the metal in small engine carburetors is a light alloy, containing zinc. My ruined carburetors have had a white sticky paste coating the surfaces inside (zinc oxide?), and when the paste is cleaned off, the metal is severly pockmarked. In effect, the fuel acts as a weak acid, and zinc is a weak metal on the nobility scale. It sacrifices ions to the solution, just like the zinc anode rod in a water heater. In my area of eastern VA, summer time humidity stays above 90% much of the time, and I believe that this can cause problems which may not be experienced in other climates. Our local Marina recently installed a 5000 gallon non-ethanol gas tank. Although they also have E-10 pumps, I notice all of the boat owners pulling up to the non-ethanol pump and paying about .50/gal more. E10 works fine in all of my on-road vehicles, and terrible in carbureted engines in my region. I am using non-ethanol gas in all of my small engines for the last year or so, and no more problem.

As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
