Thanks. I've not had a chance to really look over it properly yet. Hopefully I'll get a chance tonight.

I did engage the clutch this morning by pushing the the throttle down and rocked the mower back and forth and there didn't appear to be any resistance from the lever arm and the clutch engaged properly (or as best as I can tell without the engine running).

There was the expected resistance from the engine but nothing from the clutch so I'm fairly confident it will be fine.

Damn these midnight ponderings on how to make things work!

Thanks for the diagram.
