sorry for that. I have only one within 50 miles and happily it is close by
I found out from my local Stihl dealer that there is a Sunoco station in downtown Nashua(about 5 miles away)that sells racing fuel. It is 100 octane. He said it is about $8/gallon, but it will stay fresh for six months and not cause all these problems. Gonna get me some.
