Worked on finally getting the stator off the other motor. The appropriate tool (puller) helped greatly, but it was still a major pain in the ass. I had to put a huge breaker bar on the crescent wrench to get it to go! I bolted the stator onto the new motor and got the mag genterator ring on as well. Much constranation on which order the spark senders went in. Finally remembered that I have that Rotax assembley manual from Korea...thank goodness for that!
