Today I started the Sachs 3.2 using the method described here - choke closed, WOT, Ign Off - for three flips, then throttle down to idle, choke open, Ign on, and the engine started easily! No kickback at all. I'm very happy with how this engine starts and runs. And today it flew a 96" Kangke Monocoupe with power to spare! And I don't need a starter. Thanks everyone for your help.
