jection nozzle.
• Valve clearance is wrong
• Engine oil become thick in cold weather
and engine cranks slow.
countermeasures
• Check the fuel tank and fuel filter.
• Remove water, dirt and other impurities.
• As all fuel will be filtered by the filter, if there should be water
of other foreign matters on the filter, replace the filter.
• If air is in the fuel filter or injection lines, the fuel pump will not
work properly.
• To attain proper fuel injection pressure, check carefully for
loosened fuel cap nut, etc.
• Loosen air vent screw over fuel filter and fuel injection pump
to eliminate all the air in the fuel system.
• This is caused when water or dirt is mixed in the fuel. Clean
the nozzle injection piece, being careful not to damage the
orifice.
• Check to see if nozzle is working properly or not, if not, install
a new nozzle.
• Adjust valve clearance. (When the engine is cold)
