Av8tor1977,
As I previously said, the runs with the OS 60 would only point in a direction and may not be directly applicable. This was more a "proof of concept" than anything else. There is no question that going down in oil content will have an effect on the performance and intuitively I would say that the idle would be improved. However, I'm not sure that I would go much lower than 50:1 on oil. Gasoline( even without the oil added) has a certain amount of lubricity while methanol has none.

We have a large group of avid combat flyers in our club and they buy methanol from a distributor. Last price was $2.63/gal in 55 gal drums. I just borrowed a quart from one of them.

You can get ether by using diesel starter fluid(John Deer seems to be preferred by the diesel guys). Adding ether was the subject of discussion in one of the topics in the "Everything Diesel" forum. Basically what they do is glue a 1/8" tube into the spray nozzle of the starter fluid can and connect it to a jar with a tube going down to the bottom. The lid of the jar has a vent. They then bubble the ether through the Kerosene/oil intermittently, allowing the bubbles to go down and the propellant to vent until the mixture volume comes up to a mark on the jar. After thinking about it for a while, I believe that ether would be a much better ignition aid than acetone. However the ether content would have to be determined carefully for, I suspect that you might get into pre-ignition(detonation) problems if the content was too high. Most of the diesel fuels run 1:1:1 castor oil, kerosene and ether respectively. Some use amyl nitrate and/or MEK peroxide(Catalyst for Bondo) as an ignition aide. Since the ether/oxygen reaction is more readilly catalized by platinum than by compression, detonation could be a problem.

If you want to try ethanol, just get some denatured alcohol from a paint store. It is ethanol with about 1% methanol added to make it non drinkable.
