My name is Chris and I live in Oregon. I recently picked up a 79 or 80 C111H Serial# 100322 hoping to use it a bit this season and then do a little restoration on it this winter. Before purchasing it I looked it over pretty well and tested all functions all seemed well. I does not have the original motor. It appears to have a recent re-power with a Briggs & Stratton 12.5 HP. At any rate all seemed well until shortly after I got it home. Started it up and drove it off the trailer, all good... I shut it down to fuel it up, check the oil, etc. before mowing. When I got back on and turned the key, nothing. No clicks at the starter , nothing. I assume this is a problem with one of the safety switches. I need to start testing but could use a service manual. Would anyone know of a good place to find one? I would greatly appreciate any assistance.
