1988 7.5HP Gamefisher Fuel/Oil Ratio?

3 questions really:
1. What is the correct fuel/oil ratio for my 1988 7.5 HP Gamefisher motor (#225.581750)?

2. Assuming my current 32:1 ratio needs to change to 50:1 - would this 32:1 ratio cause a lot of gray smoke? If I still get a lot of smoke at 50: 1, any ideas on how to reduce it?

3. I've started with my idle mix screw backed out 1.5 turns. It runs there, but I don't know how to "fine tune" it from that point. What should I be looking/listening for?

Thank you for any help you can provide. - David
