Hi,
It is the slow idle mixture adjustment screw on top of the IH carburetor.
The IH carb usually needs the screw set at about 1 - 1 1/2 turn open.
The Cub operator's manual says warm up the engine before making the adjustment.

Check that the engine speeds up smoothly from slow idle speed, 500 RPM, to higher speeds.

If you are going to use the Cub in the Winter for moving snow, I suggest you drain the transmission oil and change it.
People on here have had lots of water in the trans, if it freezes in the winter, the Cub won't move.
The trans oil filler plug is on top of the trans, to the rear of the shifter.
The level plug is low on the left side of the trans, fill it until oil comes out the hole.
The drain plug at the bottom of the trans, it is visible from under the platform.
The trans holds 3 1/2 Pints of gear oil.

Water frozen in a final drive can keep it from moving too.
You have to remove the final drive oil pans to change their oil.

Checking and changing all the oils are explained in the operator's manual I posted on page 1 of this post.
The manual shows what oils to use.

Check the amount of anti freeze in the cooling system, and change the coolant if needed.
The manual shows where to fill the radiator to.
It is normal for the system to push out some coolant as the engine warms up.
When the engine cools the level should be at about the level it wants to be.
Don't keep adding water, it will push it out again.
There is probably a baffle below the filler neck, you can see below it with a light, looking to the right or left of the baffle.
Don't let the water get too low, it won't circulate. There is no water pump.
On the Cubs I have seen the level when cold should be just over the baffle, like the manual shows.
Maybe you knew these things already.

Thank you Glen, as always great advice. I tinkered with the carb today and I got her really purring nice. Will jump into doing trans oil change next. I’m a little intimidated by it but how hard can it be right? Thanks again!

Remove the drain plug from the bottom of the trans case under the floor pan and drain the fluid, don't be surprised if you find some water. If you like, you can replace the drain plug and add about 3 pints of diesel or kerosene as a flush, drive it around for a few minutes or rotate the gears by jacking up and spinning one rear wheel, then drain the flush liquid. Replace the drain plug and add 3.5 pints of 80-90 wt gear lube through the fill plug on the trans cover and you're good to go. Good Luck.
