Hi, Flashyrider About converting your engine, I have never done it, but I can tell you what I have seen in some 4 stroke/4 cylinders 1.3 L to 2.0 L ethanol powered Brazilian cars with some special devices installed at factory a) They changes the compression ratio to about 1/15 by diminishing the volume on the upper head of the combustion chamber (so you get maximum efficiency from ethanol that withstand high compression ratios) b) The ethanol needs to over 30¡ C room temperature to have enough amount of evaporation in carburettor, so they should add a preheating device or use an automatic controlled starting mixture of high octane gasoline or that is turn off when the engine reaches its working temp. c) You might add after the carburettor a hot comb or fingers made of aluminium in contact with some part of the exhaust as a heat exchanger, and add to the air intake a metal hose or cover around the exhaust of the engine if you are living in some cold climate country.

What is the best recipe for converting potatoes to ethanol. Specifically, I have a recipe that says to just boil the potatoes and use only the liquid for fermentation. Is that the best way, or should I mash up the potatoes and try to convert all the starch? 2. Does anyone have a good recipe for converting corn to ethanol? 3. I built a valved reflux still and I need to know what is the best packing to use in the column. Right now, I'm using glass marbles with a 1/2 diameter. I have heard of using Raschig rings. Are they more efficient? How about steel wool? 4. I would like to convert my 2 cycle lawnmower to run on ethanol fuel. Any suggestions on engine conversion? Thanx.
