Old Yamaha 2 Stroke Outboard Info Wanted

[Smoggy]

I have been given an old Yamaha P165 outboard from about 1971 on the basis the previous owner wants a go when I get it going, it's an 8HP 2 stroke.

Does anyone have any info on such a museum artefact as this? I'm looking for points gap and timing info mainly.

I've had it running from a bottle of aspen chainsaw fuel so far as the stuff in the tank is estimated about 30 years old, needed a clean up of the points to get sparks but I think they need setting properly, carb was surprisingly clean inside.

Someone has messed with tiller cables as first spotted ignition fully retarded and carb butterfly shut in fast position and ignition advanced and butterfly open in slow position so they need changing back.

Points gap usually 20 thou. Timing if I remember is keyed crank to flywheel. If not be about 5 degrees before TDC. But last time I worked on them was at least 35 years ago.

I had an old outboard to play with a few years ago so I googled it to see what it looked like. It's a piano.

Yeah I got that too.

It's definitely an outboard.

Sussed that bit, previous owner is left handed so sat on the other side and changed it to make it more intuative, I knew there was something wrong about him...
