ABSTRACT:
The invention relates to a carburetor for an internal combustion engine and especially for a portable small engine. The carburetor includes a carburetor housing defining an intake pipe and a control chamber which communicates with the intake pipe via intake channels. A fuel-feed line which is closable by an inlet valve opens into the control chamber. The inlet valve includes a valve seat formed in the fuel-feed line and a valve body mounted on a positioning lever which is connected to a membrane defining a wall of the control chamber. The positioning lever can be pivotally actuated to open the inlet valve to admit fuel into the control chamber. An actuating lever is pivotally mounted on the carburetor housing and can be pivoted from a rest position to an active position whereat the actuating lever applies a force against the membrane to displace the latter and pivotally actuate the positioning lever to immediately open the inlet valve when starting the engine.
