I am trying my hand at this also. I have several Echo 21cc and several Homie 25cc and a Homie 30cc to try it on. I just got the Echo going when it was dark. I am using;
10 oz. 31% methanol
18 oz. 56% gas
2 oz. Klotz KL 100 6%
2 oz. Acetone 6%
in a quart.
I still have the pull rope on it and it starts right up. Never tried by hand yet. I didn't work with it long enough to say any thing for sure but it seems to have an acceleration problem. Maybe a little more tuning? It also would run for a few seconds then bog down some and then come back. Did this when it was lean or rich, at full throttle. Had to find that perfect spot to prevent it. Had to keep the glow driver on. As soon as the meter dropped out of the green rpm's dropped. Going above the green didn't help. Going to use up this batch of fuel then try some with equal mounts of gas and methanol. Then maybe add some either. It still has the original small weedie carb on it. Am using a APC 16x8. Any body got any recent news on their projects? How about those of you that run them for some time now. Are you having any gasket/ diaphram swelling trouble? How's the fuel lines holding up?
