Carb ID and adjustment info

[Shibbershabber]

What am I looking for to ID which carb I have?


Also, where can I find info on proper adjustments?
Its been a long time since Ive payed with a carb'd engine.

The reason I ask...
Sometimes It feels like its idling high, well into my trip... already warmed up that is. Not quite as high as the high idle... but its seems high.

Other times it will start to stumble a little... Ive never let it continue to see if it will actually die, a little tap on the gas gets things going again. Once this happened I was looking in the side mirror when hitting the gas and I had some black smoke when I hit the gas.

Occasionally get a strong smell of gas when getting out of the truck, but I have no visible fuel leak.

Though even if its all unrelated, itd probably still be a good idea to know what I am doing and to have the carb properly tuned.

thanks
