Adjusting the valve clearance on the lash-gouges using a probe or rod with an indicator at first glance is a very simple operation. But in reality, the gap in the valve mechanism, and its magnitude, on any engine, is quite a serious and responsible thing. When you configure it, there are a lot of things that you should pay close attention to. From the clearance in the valve mechanism, and of course from the state of the mechanism itself, the compliance of the gas distribution phases contained in its design directly depends. And only in that case when the timing mechanism works as it should be possible to obtain the maximum power characteristics of the engine.
