Hate it when that double post thingy happens. I messed around with E85 a few months back in my SuperTigre's and found it to run quite well. Yes, I did have to run a different glow plug, specifically an OS A3 to replace an OS #8. After the plug change it idled just as good as 10% glow fuel. I then added 10% NitroMethane to my brew to try and get my power back which worked. All in all, it turned out to be a very good fuel. I have since converted it to Gasoline/Spark ignition with good results and that's what I am currently running it on.

Downunder, I have run automotive engines on ethanol with the C/R as high as 13:1 with no hint of detonation at all. Can't say how it would react with the C/R that high in a model two stroke as there are other factors involved such as the oil dilution which in theory should reduce the antiknock qualities of the fuel. That's just speculation though as I haven't tried raising the C/R on a glow and then running E85 in it.
