I have a shindaiwa 21cc motor on a super stick 60 and i have a problem. I had the motor running great the other day on the plane and i flu it but it was a little rich. So i landed and richin it up but it was to late to try it again. The next day i tried flying it but i had the radio on the wrong model,and time i took off it rolled over and hit the ground. I fixed the plane and tried it the next day and now if i have it over half throttle it is missing and cutting back the whole time i'm flying it. I took the carb apart and cleaned it and it still does the same thing. I checked the timing and its about 27degs. Can someone tell me what they think might be wrong with it? O yes i have EI on it that i wired up from parts that i got off web. Thanks for any help.

Thanks
