Engine Management Exhaust emissions are controlled by the design of the fundamental engine parameters and components (e.g. carburation, ignition, timing and valve or port timing) without the addition of any major hardware.

These power tools are equipped with different carburetors: Version A HL LA - High speed screw and low speed screw with special head - without slotted head.
