All Hyundai chainsaws use Walbro carburettors, so the tuning principles are the same.
Carburettor adjustment is critical on chain saws and other two-stroke engines. An engine that is running too rich will cause a saw to smoke, have insufficient power, result in additional carbon build up and may damage the engine. An engine that is running too lean will also produce insufficient power and is more likely to damage the engine from piston/bore seizure. The correct carburettor adjustment will allow the saw to produce maximum power, extend the life of the engine, reduce emissions, idle smoothly, rev up quickly and give long trouble free service.
