I tried it on some Echo 21 to 25cc engines, and some Homelite 25 and 30cc engines, with varying compression ratios, various glow plugs, with full time glow power and without, and various mixtures of ethanol based fuels. For me, the results were unsatisfactory. As I mentioned, others here have had some varying degrees of success, and a search will bring up their threads. The glow plug really needs methanol for proper catalytic reaction with the platinum in the plug. OS Engines briefly advertised that they were going to release some engine(s) that were set up for ethanol fuels, but I haven't heard any more news, nor seen any of the engines yet. Perhaps they found it wasn't feasible, I don't know.

I settled on our present "Gas/Glow" system (using methanol based fuel and gasoline), as being the best all around compromise, and they work very well. Good luck on any experiments with ethanol and glow plugs, and please keep us updated on your progress.
