points .020,plugs .030. carb slow 1 1/2, high 3/4 from lightly seated and then adjust to obtain best running.im not 100 percent sure weather its 40:1 or 50:1 fuel mix.

The port on the backside of the midsection is the indicator.

Mix 24:1 gas:eek:il and use TCW-3 oil. That motor won't pee a steady stream like modern motors. You will see water spraying/dribbling out the exhaust relief port if it's pumping properly.
