When a new decompression device is
installed the correct function must be
checked. To do so install the
decompression device with the 0.4 mm
(0.0157“) thick gasket, continue with
step 14, 15 and 16. Turn the piston
approx. 1/8 revolution before TDC and
measure with a depth gauge the
distance between bracket for rocker arm
shaft and spring collar of the inlet valve.
Next, activate the decompression device
and measure the distance again. There
must be a difference between the two
measurements of o.7 - 0.9 mm (0.0236-
0.384“). If it is less than 0.7 mm
disassemble the decompression divice
and replace the 0.4 mm (0.0157“)
gasket with two 0.3 mm (0.0118“)
gaskets (in extreme cases use one 0.4
mm and one 0.3 mm gasket). Carry out
the two measurements again.
If the tolerance is more than 1.0 mm
replace the 0.4 mm gasket with the 0.3
mm. Carry out the two measurements.

14. Push rods and protection
tube
Slide the protection tube down onto the
decompression device. Assemble the
retaining spring in the top of cylinder
head exactly as shown but do not
tighten the nuts yet.
(Figure 32)
Insert the push rods through the
protection tube into top of the
decompression device. Both push rods
are alike. The intake push rod goes into
the hole in decompression device
closest to cylinder.
