I found this link http://hrsbstaff.ednet.ns.ca/bvogel/...wont-start.htmon the German forum www.flyingBrick.de. It's a well written, semi-non technical, description of how all the various components associated with getting a K100 to start and run properly. Looks reasonably accurate and might be of interest to K100/K75 owners.
Check it out.
