I have an Emerald III in my 1979 Avco and I was wondering,, that isn't original equipment is it? If not what year was the Emerald III introduced thanks again Tom.
The iii had points and condensor in them in the distributor in the back side of the engine. Also a coil. I dont have the manual anymore. I got quite a bit from onan web site. Now its cummins onan.
