Abstract
An engine fuel supply apparatus includes: a fuel chamber provided in a carburetor; a first communication passage for opening the interior of the fuel chamber to the atmosphere; a second communication passage for communicating the interior of the fuel chamber with the interior of a Venturi section; and a passage switching section capable of switching between the first and second communication passages and mechanically connected to the main switch so that it can operate in response to the main switch shifting between an ignition position and a stop position. The passage switching section switches the second communication passage to the first communication passage in response to the main switch shifting from the stop position to the ignition position and switches the first communication passage to the second communication passage in response to the main switch shifting from the ignition position to the stop position.
