compression
no valve clearance
Check and adjust the valve clearance
Under very low
temperatures
Too high fuel viscosity die to insufficient
cold resistance
Fill in a temperature resistant fuel mixture
Starting speed too low (viscosity of oil too
high)
Change the lubrication oil and fill in oil of
correct viscosity class
Black exhaust
fumes The en-
gine power may
also be low
(speed drops)
This is not
caused by the
injection pump
