Darin,

Thank you for the explanation. This makes perfect sense now.

I tried to mix Coleman camper stove fuel with methanol and was unhappy with the results. I used Amsoil Saber synthetic oil. It did not help hold the mixture together any better with or without the addition of this oil. I was able to dissolve about 15% gas into 85% pure methanol but this did not allow me to use that stock carb as I was hoping for.

After looking at many threads I came to understand that I need either E-85 or ethanol if I want to mix at a higher ratio, but E-85 is not available here in Eugene Oregon. We don’t have air pollution at high levels yet.

Denatured alcohol would also work, but it cost too much.

So If I want to use Methanol it looks like I have to buy a new carb or I should stick with magneto ignition on Coleman stove fuel.

Since I from the cheap school of aviation science, or perhaps you could call it the Lawn and Garden Aviation Center, I’ll just have to accept the weight of the flywheel and coil.

I’m always looking for other suggestion.
