VERY interesting dissertation by wvarn1957-RCU, and we thank you. One point however... I'm afraid that the high lead content in aviation 100LL could be a problem in our low compression engines. Generally, unless the engine has enough compression, (and heat of combustion) to need the lead for detonation suppression, the lead causes spark plug fouling. This has been a major problem in the airplanes designed for 80/87 octane, that were forced to use the 100LL after the older fuel was phased out. I think this could be a problem with our model engines, with the lead fouling the glow plug, and/or causing a lot of carbon build up. Other opinions???

wvarn1957-RCU, if you were to mix some acetone with gasoline to enhance the catalytic reaction, what ratio would you use? If you were going to try this, what would your recommended fuel be, with cost, reliable operation, and ease of use being the criteria.

Thanks,
