I did squeeze the plug wire just a little with pliers. I used a small needle nose pliers and was careful not to bend anything enough to damage it. It does fit noticeably tighter now. I don't think there's any chance of it coming off, but you can rotate the wire on the plug. It's still not as secure as a automotive plug wire would be, but it's probably ok.

This engine doesn't have a C&H ignition, I don't know if FPE makes it, but I have never seen another like it. There's a coil and a little black bag containing the other ignition stuff. The ground wire from the coil is attached to one of the engine mounting bolts. The wire from the sensor by the hub can only plug into the connector from the little black bag one way, so it must be correct. I need to double check the wire from the coil to the little black bag. I am not sure if that wire can be hooked up backward or not. I did get the engine to fire this time.

After several flips, it was 24 degrees here so I didn't expect it to start on the first flip, it fired with the choke closed and the throttle wide open. That's how the instructions said to do it. The problem is that it wants to run backwards. I am not overly comfortable flipping an engine that wants to run backwards. After the engine fired with the choke closed, I opened the choke and set the throttle at what I thought was just above idle. It fired with the choke open, but it still wanted to run backwards.

What could cause this? Could I have the throttle too far open? I am tempted to try starting it with my Sullivan Dynatron.

Thanks for any info, this forum is really an excellent resource.
