This invention relates to a flexible intake system for a crankcase scavenged two-stroke internal combustion engine () having an additional air supply to its transfer ducts. The intake system comprises a flexible intake duct () connecting a fuel supply unit () e.g. a carburetor with an engine cylinder () and at least one flexible air duct () connecting a valve housing () for additional air with the engine cylinder. The end portion of the flexible intake duct () and at least one air duct () is secured to the cylinder by means of a baffle () made of a stiffer material than the ducts () themselves.

Flexible intake system for a two-stroke internal combustion engine

The present invention relates to a carburetor of an internal combustion engine having a manually activated start position. The carburetor includes at least a choke valve and a throttle valve both located in the carburetor's main air passage which are able to move between an open and a closed position, each valve having at least one respective lever that cooperates during the manual activation to give at least one start position of the choke and throttle valves. The carburetor further usually includes at least one thermally responsive member arranged to affect the start position. Further a handle is arranged to provide a two stage draw&#x2014;lift motion to attain the start position.
