Got the wingplates off, had to remove the powerhead to get the bolts out...
Tiller is on, although the cables aren't connected.
The throttle cable on the engine is pull to open, whereas the tiller is push to open. Think I read somewhere about reversing a gear inside the tiller to fix this? Anyone know? I also appear to be missing a bracket of some sort to hold the cables in place, going to google it and see what I can find.
Looking at the engine more closely it looks like it is a genuine CES, or 90% CES parts, Here's a couple photos of what I mean about the cables.
