Something aint right here as the alternate firing Johnson KS-15’s were only built for two years, ’41 and ’42. That serial number has to be 43XXXX if it really is a KS model. Could it be a KD-15 with the rewind starter as they were built thru ’48 and the 48XXXX serial number would qualify it for a later KD-15? What color is it, green or silver?
These are smooth running motors and well worth the effort to get them running. They like to drink 8:1 fuel mix, not 16 or 24:1.
