Other components that have been used on carburetors include:
* Air bleeds allowing air into various portions of the fuel passages, to premix air and fuel, and minimise vaporization, and to largely correct air/fuel ratio over a large range, typically referred to as the [[emulsion]] system. 
* [[Miss Shilling's orifice|Fuel flow restrictors]] in aircraft engines, to prevent fuel starvation during inverted flight.
* Heated [[Vaporizer (internal combustion engine)|vaporizers]] to assist with the atomization of the fuel, particularly for engines using [[kerosene]], [[tractor vaporizing oil]] or in [[petrol-paraffin engine]]s<ref>{{cite book |last1=Hutton |first1=Frederick Remsen |title=The gas-engine.

* [[Early fuel evaporator]]s
* [[Feedback carburetor]]s, which adjusted the fuel/air mixture in response to signals from an [[oxygen sensor]], in order to allow a [[catalytic converter]] to be used
* Constant vacuum carburetors (also called variable choke carburetors), whereby the throttle cable is connected directly to the throttle cable plate. Pulling the cord caused raw gasoline to enter the carburetor, creating a large emission of hydrocarbons.<ref name="Stermer">{{cite book|first=Bill |last=Stermer |title=Harley-Davidson Motorcycles |url= https://books.google.com/books?id=Rkj8y8QYppMC&pg=PA154 |publisher=MotorBooks International |isbn=978-1-61060-951-7 |page=154 |date=2002}}</ref>
* Constant velocity carburetors use a variable opening in the intake air stream after movement of the throttle plate from the accelerator pedal. This variable opening is controlled by pressure/vacuum at the variable opening itself. This pressure-controlled opening provides relatively even intake pressure throughout the engine's speed and load ranges.
