Hello fellow enthusiasts The 125 has been converted to 40:1 Amsoil and 90 octane after break in with 32:1. I am a "if it ain't broke done fix it " The engine performed flawlessly at the field with no needle adjustments. Starts easy transitions excellent at factory settings. Developed 5854 rpm with a falcon 23/10 and flew 28 pounds with no more than 1/4 throttle on the Phoenix 60 Waco. Flew it un cowled for first flights. Baffle on. Temps 140-150 consistent across all cylinders. Very pleased with the engineThe sound on low passes is breathtaking..
