The high octane level in premium is not needed. The Ethanol,,, how ever can and does cause problems. Ethanol carries moisture and the moisture is what causes most of the problem with the carbs. There can be corrosion and deposits in the float bowl due to moisture. There can be a gum deposit from the ethanol dissolving years of film off of the tank and that gum then hardens in the bowl and jet passages. The fuel can and does.... dry up and scab over jets and passages from the scum and gum in the fuel from the ethanol removing it from other places. And carb venturi design using particularly small passages will totally clog up from using ethanol fuels, again from the gum and scum scabbing over and stopping up the passages. Running the carbs dry with a cut off valve will MOSTLY stop this from happening on a lot of small engines. Engines with either solenoid loaded needle cutoffs or large jet design seem to tolerate the ethanol very well, so modern designs seem to do better. SO... you do not need high octane. You may or may not have problems with the gas drying up and causing flooding or a very lean run or a no run due to ethanol gas. Non ethanol fuel, if you can get it and afford it, will have less problems. Running the tractor often, will mean less problems as oppose to letting it sit for long periods and having more moisture and evap problems. Again, cutting off fuel and running carb dry before you put the tractor/chainsaw/welder/generator/weedeater/........ up, seems to solve/help this problem.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
