I have an old Yamaha EFC 200 CDI
It runs and puts out power O.K. but only runs at about half speed. It seems as if it is only firing on every second compression. I have checked the carby jets and air cleaner and float level all O.K.
It seems to be a problem with weak or erratic ignition.
Is there a CDI ignition unit some where? If so where do I look for it on the machine, and where do I get another one if needed?
