Remember those settings are 'starting points'. Once motor is warm adjust low speed again. You'll have to dial in high speed mixture on the water at WOT
HI kikkup. Welcome to iboats. This link should help you get the carb set up. Be sure you run your motor in a test tank with water filled up to about 1-2 inches below the exhaust port. These older motors can't run on muffs. Good luck. Keep us posted.
