Well converts I have some good news for you, I finally got to work with my project and got some interesting results; First of all let me tell you that I went directly to the head of the snake and tried the gasoline/ether/methanol/oil combination and compared it against the straight gas/oil mixture and got some interesting results.
Engine Ryobi 31 cc, Prop APC 16x8, gasoline 87 octane 50:1 oil mix ratio, at sea level. For glo plug version an O.S. 4 stroke plug was used.
Results:

1.- gasoline/oil with magnetic coil/flywheel ignition = 8500 rpm's, 2.- gasoline/oil with glo plug/2.4 battery volt constant current = 8400 rpm's and good idle at 2200 rpms.
3.- same combination as 2 but once started the battery was removed = 8300 rpm's, rough idle and stoped. 4.- gasoline/oil 75%, methanol 20%, ether 5%, magnetic coil/flywheel ignition = 9200 rpm's real smooth idle at 1800 rpms and smooth throttle transition.
5.- same combination as 4 but glo plug/2.4 volt constant current = 9200 rpms, smooth idle and throttle transition at 1800 rpms
6.- same combination as 5 but once started the battery was removed = 9100 rpms and good idle like a glo engine, smooth throttle transition at 2000 rpms
7.- gasoline/oil 65%, methanol 30%, ether 5%, with glo plug/2.4 volt battery constant current = 9200 rpm's, smooth idle and throttle transition at 1800 rpms.
OBSERVATIONS: When mixing the Gasoline/oil mix with the methanol you could see two layers of non mixing solutions but when the ether was added it became completely miscible(fully mixed) homogeneus solution. When starting the engine with the gas/oil, methanol,ether mixtures the engine would start very easy (with regular electric starter) but some times I would feel a slight kick back but no big deal.
CONCLUSIONS: So far this experiment indicates that the glo plug system can be used instead of the very heavy coil/flywheel system saving us this way alot of weight and giving us the fuel economy and low engine cost that we are all looking for, although the use of ether complicates a little bit the manufacturing of the desired fuel but I think we can find a way to solve this matter. ANY IDEAS ANYBODY ?.
I Will keep on experimenting on this issue but I hope that anybody can come with some comparisons and results that can validate this experiment.
P.S. I also tried a 10% ether combination but the result wheren't better than the 5% ether combo.
