Yes ! ran my 7-35 with the 5% fuel mix tonight and now it actually sounds like a radial engine!

I was i bit turned down over the sound when i first ran it with the 15% oil mix it was sooo! quiet ,but i got a good surprise today. I have learned that the high oil mix takes away the sharp sound of a radial. Now it rumbles like a m14p! hehe

I will also test my ASP 400r5 with a lower oil mix , it will probably also sound much more like a radial then.
