Adjusting the Valve Clearance of KAVAN Four-Stroke Engines

The valve clearance is adjusted when the engine is assembled at the factory and does not need to be adjusted in normal operation. However, after a longer engine operation, the performance may decrease (as well as after dismantling or repairing the engine after a model accident) and the clearance adjustment is necessary. For this purpose, you can use the O.S. Engines No. 72200060 set containing two gauges and two hex keys or purchase 0.04 and 0.10 mm feeler gauges and the corresponding tools (2 mm hex key, flat wrench No. 5, small flat screwdriver) from a specialist shop.
