It appears to have 3 steps of high idle that depend on the temperature. It stays on one step until I lightly press the gas, then it drops down to one of the lower steps or steps off of fast idle completely, depending on how warm the choke is. This is my interpretation of how it is working, I could be mistaken.
Nope. Looks like you got 'er working just right. Might need more adjustment for different weather, but probably not much.
