Abstract

This invention relates to a flexible intake system for a crankcase scavenged two-stroke internal combustion engine (10) having an additional air supply to its transfer ducts. The intake system comprises a flexible intake duct (22) connecting a fuel supply unit (21) e.g. a carburetor with an engine cylinder (11) and at least one flexible air duct (40) connecting a valve housing (42) for additional air with the engine cylinder. The end portion of the flexible intake duct (22) and at least one air duct (40) is secured to the cylinder by means of a baffle (23) made of a stiffer material than the ducts (22, 40) themselves.
