Any Koher CV22 experts out there?

In the process of inspecting and repairing and replacing parts, I found several shroud screws missing and a couple broken off in the lugs on top of the cylinder heads. I removed the fan shroud to make access easier and discovered a little black electrical module mounted on the outside of one of the cylinder side shrouds, next to the starter. This module is described in the parts catalog as p/n 24 584 05 "module, speed advance" and it has had all the wires clipped off of it. No evidence remains of where the wires might have gone to.

The engine started up and ran fine, but I never drove or mowed with the mower as the hydro pump belt was busted when I got it, and I've been disassembling and replacing parts ever since.

Any ideas what this module does, or why someone might have clipped the wires? Is it some sort of electronic spark advance?

Where can I find wiring diagrams that will show where the wires connect if I decide it needs a new one?

It is marked as a CV22S but it is a spec number 67513, which makes it a straight CV22 without the "S".

I located the part using the parts breakdowns on the M&D mower web site (very helpful I might add)

Thanks for any advise anyone might have.

Annoys me no end when I find a company that wants to charge for an online manual for a product they built!

All these manuals today, and for the last 10+ years, have existed in an electronic format at some point prior to printing. Isn't much trouble to buy a copy of Adobe Distiller and create PDFs for people.

I have no problem with charging for printed editions, or for on-line editions my companies that re-print manuals or made electronic editions for out-of-business companies or very old products that never had electronic versions of the manuals to begin with.
