Valve clearance on a Vetus M4.17

It was time in FL's maintenance schedule to check/adjust the valve clearances. 


Rocker cover removed


Turning the crank to get piston one to Top Dead Centre



TDC achieved when the pulley timing mark aligned with block timing mark.


Inlet and exhaust valve can them be adjusted too 0.25mm
 Pistons 3, 4 & then 2 valves are adjusted after turning the crank 180 degrees after each pair of valves are adjusted.
