In a moment of weakness, I ordered a 25 LA-S, and ran it for the first time, today. I have it mounted in a profile Smoothie, with a uniflow tank using muffler pressure, GMA 10/22 (50-50) fuel and a Zinger 9-5 prop. Filled the tank, flipped it 4 times with finger over the venturi, two flips with open venturi, hooked up the battery -- first flip start. I leaned it out to a 2 cycle and then backed off to a hot 4. What a beautiful running engine! Gonna fly it rich, tomorrow. Will report.......Glen
