How to match the throttle of Wuling Hong Guang b 12 engine?

The engine directly driven by the valve tappet can't adjust the valve clearance like the engine with rocker arm or swing arm structure, so it is necessary to choose a valve tappet with appropriate thickness to replace the original valve tappet according to the distance from the base circle of camshaft profile to the top of the valve. If the valve clearance is large, replace it with a tappet thicker than the original thickness, and then measure the valve clearance after installation. If it is within the required range, it is ok.
