[ROVERNET - UK] A slow death

What do you mean by "cozies".  In Australia we would think this means swimming
costumes.  I wonder if there is some issue with cranckcase ventilation, the
flame traps and oil fumes possibly fouling the plugs.  It would seem that
you have an overheating problem because of the temperature rising with slower
air movement through the rad core and perhaps you will need to check that
all through, core, pump, sediment in the block, coupling of the fan and pump,
thermostat, timing etc ad naseum.  With the engine hot excessive oil smoke
from the flame traps or oil filler may mean excessive blowby indicating the
rings are worn.  As the engine gets hotter the oil may release more smoke
which may change the operation of the flame traps and hence the air balance
in the carby's and or begin to foul the plugs.  This in turn may effect the
vacume advance, which operates via a vulnerable pipe to the distributor.
  Try changing the oil and the plugs to a higher heat range and clean the
flame traps.  I presume the heat insulators were fitted when the carby's
were re installed.  Inspect the vacume pipe.  When the idle falls does the
engine misfire?.

Let us know hoe things go Good luck Roger
