Clif Dyer did an inspection and everything was good except one jam nut on the throttle and one on the mixture. Performed another taxi test and all was good. Brakes working good, no leaks oil or fuel. Filled both taks and calibrated fuel guage on Dynon. Right tank burpped fuel all over ground when I was not looking, almost made me sick. I thought I had a monster hole in the tank. Thank goodness it was just air in the tank, NO LEAKS!!!!!
