  12. Functions of a carbuerator?
    • mixes fuel and air
    • meters fuel
    • controls air flow
  13. how are carbuerators classified?
    • barrels
    • CFMs (size)
    • fuel type
  14. What is the Venturi?
    • where air horn bottlenecks
    • creates a vaccuum by lowering air pressure and increasing air speed
  15. What does the Choke Valve do?
    controls amount of air let into the carbuerator
