Well I finally got to fly the Cub today with the new Evolution 46 NX. What a difference. After priming and a couple of flips it was running and sounded good. I have the HSN a little on the rich side for now until I get some more time on the engine. I flew for almost 15 minutes and not so much as a hiccup. After I landed I checked the fuel and still had around a half of a tank left. At least I can fly it now until I get my Saito Fa 62.
