Many generators start out with 111. 1112700 would be logical Delco number for a generator. My book is dated 1960 and it is not listed, but it could very well have been superseded. A generator shop with complete Delco books could chase it down. It is very common for incorrect parts to be installed by previous owners. If the engine is any where near original it would have been 6 volt. I would install the 6 volt coil and worry about the generator once you get the engine running. Make sure you do not use any stale gas to try to start it. Stale gas can cause valves to hang open and cause serious damage. I usually bypass everything and I hang an aluminum gokart tank about 2 feet over the carb. Are you getting spark? I have seen points gapped way to wide and no gap. Your carb may be plugged up which of course will be another issue. When I buy a jalopy that someone else has replaced parts on, I assume all the parts to be wrong, and if a part is correct, I consider myself lucky.
