If it would ever stop raining here in Mayland I would go out and test out this new Wildcat YS 20/20 fuel. It has rained every day for the last week at least. I am hoping for a more consistant needle valve setting, it seems every time I run my 140L I have to make an adjustment to the needle...I set it then it goes lean for some reason and the second flight I have to richen it up a half turn
