Thanks for the info guys.
Alan I have done all that you have suggested in regards to carb adjustments. This is not my first rodeo. This thing has me totally stumped. the fuel, yea I know, not the best to use. It is the end of our flying season and I had a small amount to use up. I bought it from a local shop when I was on a trip and didn't realize what I had until I got home. I asked for some 15% and that is what I got! The shop was probably trying to get rid of it, and pawned it off on a non local dude. In regards to the OS#8 plug, I don't have any of those. I do have some Fox Miracle plugs, how close are these to 8's. I live in a rural area and do not have acsess to a local hobby shop. Most of my stuff is purchased through Tower. Know matter the remedy. I probably will not be able to test any theory until next spring, as I live in Northern Michigan and the flying season is about over unless we have unseasonal weather.

Thanks all for the input.
