3 hp lightwin

[airshot]

I have found a 3hp johnson lightwin outboard. It seems to be in very good condition. I have searched for info for this motor on this forum, but have come up empty. Compression is 80 lbs on both cylinders, but need to know how much spark gap these small outboards should jump. Also need year if possible
model # JW-19M, serial # B123 176 Any and all information is greatly appreciated.....

1964 Model. With a spark tester, you should jump at least 1/4 inch gap.
