Thanks for all the replies everyone.

I looked at the shaft a couple of times and could not find any holes or flat spots. This is the original outer shaft. Is it possible to put it back in upside down?

I have pressed the two swash plates together and they snap in place. However, as soon as the throttle is going a little and I use the right stick, the lower swash slides down.

It looks like I have a few things to try this evening.

Thanks again.
