Small semantic point Kori: the automatic choke is controlled by temperature and intake suction. The Choke-A-Matic is a coupled choke, not an automatic choke, so when the speed control is advanced to the Choke position, the choke closes, and you have to open it manually when the engine starts, by moving the speed control from Choke to Fast. So, this engine has a Briggs automatic choke, not a Choke-A-Matic. Incidentally, the Choke-A-Matic is the same system Honda still uses. Not nearly as nice as an automatic choke, but considerably easier to maintain in the field.
I hadn't heard previously that the 110000 series engines did not have a kill switch. Can you Kori, or anyone else, post a picture showing how the engine stop system works in practice? It is an essential safety requirement that after stopping, the engine cannot be restarted just by rotating the crankshaft - it has to be switched on in some way first.
