Thanks for the video! Was stuck with mine! Some questions...! 1. So do you screw in to the piston pin to pull it out? 2. Did you mark the valves to put them back the same way or does it not matter? 3. How did you clean the engine? Ultrasonic with Degreaser or carb cleaner? Or some recommend the antifreeze hotpot? Thanks!
