That autolight #386 is a resistor plug and may not work so well on your motor. A champion D9 or 509 plug may be what you need. Others will chime in on this as there are other plugs available. Sometimes the model and serial number will be stamped somewhere on the cylinder or the crankcase.
My mistake, a champion D16 or 516 plug gapped 0.025" is what is recommended in the old outboard book. The book also notes point gap set at 0.018 or 0.015". Gas oil ratio is 3/4 pint to a gallon 30wt oil.
