1.7 Measure cylinder compression clearance height
(1)Disassemble cylinder cover, put fuse ф1.5×10mm of the same height on the four points of
piston top, reassemble cylinder cover, screw on cylinder cover bolts according to the stipulated
order and torque.
(2)Revolve crankshaft in anticlockwise direction, flat fuse, disassemble cylinder cover and take
