Abstract
A carburetor includes means for detecting the volume of a first fuel such as gasoline within a float chamber, and valve means for preventing a second fuel such as LPG from being fed into an induction passage leading to an engine when the volume of the first fuel within the float chamber is above a predetermined value. The second fuel is prevented from being fed into the induction passage until the volume of the first fuel within the float chamber is decreased to a small amount or zero. Thus, the air-fuel mixture within the induction passage is not enriched too much after the fuel supply is changed from the first fuel to the second fuel.
