For a Liberty Kid, you actually want a reproduction Lunkenheimer or Essex style brass mixing valve instead of a modern carb. A lot of antique hit-and-miss engine restoration shops sell brand new brass ones. They run entirely off the vacuum from the intake stroke to pull fuel past a simple needle valve. Super simple setup.
Wow dude 😂❤ you really are one hell of a mechanic you have gotten some great luck with making this and the washer run pretty dang good !!!!! Keep up the great work
When the engine is running you will notice smoke coming out of the hole in the top of the cylinder head. This hole should have a priming pot installed in it. The pot will have a valve at the base that allows you to close it off after a small amount of gas is put in the cylinder when the engine is cold. With this hole open you are losing compression.
